Hi everyone,
my data plan covers 3G and also HSDPA......im currently using the JF1.51 and when i use the go online with the device, it only shows the 3G logo....... does cupcake only cover up to 3G instead of HSDPA?
if anyone knows, please tell me, thanks alot....
p.s. i tried the Hero rom last month and after setting the APN, it showed "H" instead of "3G".....does it mean that the Hero rom has "unlocked" the HSDPA function?
thanks alot

The H in Hero is just a custom icon by HTC. All Dreams are capable of HSxPA regardless of whether that icon shows up or not. As for the carrier side, you are most likely on HSDPA. If you are on any T-Mobile network or most Asian networks (Taiwan, Japan, China) they are HSDPA. An easy way to verify is to start a speed test. Any speed higher than 384Kb/s downstream (384Kb/s ~= 48KByte/sec) means you are on HSDPA.
If all that was too complex, just assume you are on HSDPA.

I had thesame issue with the Touch Pro on sprint, it only shows the EVDO icon when connecting, however, sprint is even advertising their new 4G network but I have not seen my phone ever go to 3G or above. I thought something was wrong with my phone...
I went to sprint to get it exchanged because I bought the phone for the faster service. I was given a big spill over the offered network on sprint.
Your answer: Basically, some icons are not unlocked in some roms or are not even included depending on your service provider. This being said, you will most likely have to have the custom rom to get this to show up on your phone.
But even if your phone does not show that icon, test it and see if it uses the technology.
- What I did is took my TP to my friend who has the new Iphone 3G and we started the YOUTUBE app and loaded the exact same video. Even though his showed the 3G icon all the time and mine only showed EVDO, my phone brought the video up almost 5 seconds before the Iphone ever did, not to mention the quality of video is so much better.
Ok, I see that I am rambling, I hope that this helps though, however, if I have been informed incorrectly, please someone correct me because I would like the other icons too, just for my aesthetic needs.

Your rom can't give you cdma support, that is hardware related. And the G1 is only on GSM networks not any CDMA's so you might have seen some other type of icon because it is not possible to get EVDO on any G1.
these were my thought exactly...but i promise and swear to you it said EV not evdo but EV and my connection was faster than ive ever seen before..im going to get that screenshot capture nd next time wen i go to the spot where it happened i will show you...dont know how its possible or what it was..but it was super fast

I aint saying I don't believe you, I just know it is impossible to get CDMA on a G1 no matter what rom or dump. What I would assume is it was HSxPA and the rom you used had a dump from the sprint hero. That could explain why you had a EV icon and is most likely what happened. Like the other guy said his touch pro had a EV icon although it was getting 3G, so since you do have a 3G icon and it switched to EV it is probably because the area you were in had HSxPA.
yea that makes sense but wow was it fast..thanx for the input
HSUPA gets like 7.2mbps so it is like cable almost, I'm not sure about HSDPA but its is pretty quick too.

Go somewhere that has t-mobile 3g coverage. That is the only way to get the speed you inquired about. If it's not in your area yet, be patient. They are doing alot of expansions to their network. If you live in a rather remote area (ex: somewhere that doesn't have EDGE coverage) don't hold your breath. It's gonna be a while.

HSDPA and HSUPA are both 3G telephony protocols in the HSPA family. They are two parts of the same thing. HSDPA (Downlink) provides up to 14 Mbit/s. HSUPA (Uplink) provides up to 5.8 Mbit/s.
btw HSPA (or 3g as US carriers call it) is CDMA. Though different from CDMA2000(EV-DO) which is what you were refering to, UMTS is still CDMA based.
And to those confused about the Icons. 3g and HSPA are two names for the same thing. The icon you see simply depends on what the common name for the technology is in the locale the rom was originally designed for. Google based roms usually show 3g whereas HTC based roms sometimes hav H instead. The only difference is the icon.
as for those with EV icons. They are probably from the samsung galaxy system dump. Not to say it's not out there, but I haven't heard anything about a sprint version of the hero rom surfacing yet.
Ohh I guess I didn't have it right. But I know I have seen something about HSxPA gettin 7.2. Damn 14mbits is insane for a cell, I wish I got that in my area. My DSL is only like 7mbits dl and 1.something upload.
Should get it eventually. I only get 7.2 as well, but t-mobile has the whole 1700 band leased, so we might get lucky over the next few years.
Hello I seem to have a problem and I am hoping someone can help. My phone is rooted running Modaco r20 Desire Rom. Radio is ERE27. I have a strong 3G signal in my town with T-mobile. My problem is that for some reason whenever I use data (internet,online gaming, searching using apps etc) the icon will stay on 3G then switch over to H. Sometimes it will stay on 3G and it will not allow any data. I know about the EDGE to 3G issues. I don't seen to have that issue. Can anyone help and or know why this happens?
Usually, when browsing the internet or anything is being downloaded at all - the 3G icon will switch to H. Really only in custom ROMs though, I don't really believe this happens in the stock ROM.. it's not a bad thing or a problem, at least not for me.
Data doesn't completely shut off for me though.
The "H" means you are achieving an HSDPA connnection of sorts. Stock does not have this icon in it, since HSDPA is a form of 3G and they didn't want people getting confused by it switching from 3G icon to H icon.
HSDPA is faster than basic UMTS, aka "3G"... so it is not a bad thing at all.
No idea why you loose your data connection all together when it switches, since it isn't doing anything other than recognizing you have a faster data connection than basic 3G, nothing is actually changing to cause you to lose your connection since it is still the same connection.

no it is not...
mine does the same thing... i have to twiddle my thumbs and wait when it switches between UMTS and HSDPA... they are different frequencies just like EDGE is on a different frequency...
I don't think UMTS and HSPA are on different frequencies, the same two frequencies are used (alternating for downlink/uplink) for both, those are 1700mhz and 2100mhz.
For some reason I don't have this problem on Long Island, but when I'm in the city this happens the whole time. Might be something to do with the way the network is configured. Basically whenever data is in use, it just says 3G, but as soon as I browse to a site or actually use data, it switches to H within a second or so. I think a stock ROM would technically be doing the same thing, but it just won't show the actual switch, as it doesn't differentiate between HSPA and UMTS in the top 'taskbar.' Although it would probably show this in the phone status screen under settings.

The "3G" to "H" (and back) is a "red herring". If it's "stuck" on 3G when you're trying to do data, it means your handset is having issues communicating in the AWS bands for 3G (2100/1700) and the handset hasn't dropped back to GSM/GPRS/EDGE (1900) yet or is attempting to switch frequencies and the associated towers aren't cooperating with the hand-off or the hand-off is failing.

I'm in times square. My phone has never switch to UMTS. Either HSPA or EDGE.
also while it's idle it will only use 3G
it will switch to H to transfer data, then revert to 3G

Which Modaco ROM? If it is Desire, you have to flash the newest radio, and do it after flashing the ROM itself, otherwise you will have major Radio issues... at least that is my, and a fair number of other's, experience.

Yeah its Desire rom. I have radio ERE27 right now
Try upgrading to the newest one, 32.26.00.24U_4.04.00.03_2:
http://android.modaco.com/content/g...-online-kitchen-optional-root-insecure-himem/
Make sure you have at least 50% battery before flashing, just download and flash via recovery just like a ROM, do not panic, ever, during the process and do a battery pull, just wait for it to flash, then ask you to reboot, reboot, it will then do the actual radio flashing (you will see a box with arrow screen for a couple minutes) it will reboot on its own into recovery, say "writting" cache with a progress bar for a few seconds. The bar will go away, but the "writting cache" text will not, don't worry it is done, just reboot and then double check it flashed by going to about phone, software, and checking baseband version.
Just remember, can't stress this enough, do not pull your battery at all during this process. And make sure you have at least 50% battery before starting. Flashing a radio is the only way you can brick an N1 right now, and only if you pull the battery during the process, or have a bad download. Speaking of which, I do recommend checking the MD5 sum to make sure it is a good clean download.

I'll have full bars for 3G and when I goto check the market or anything internet related, the 3G will switch to H and work or stay at 3G and pause with connection error, retry or cancel.
I started having this issue after updating my factory stock radio. Anybody know which one is the stock/default radio IMG is? I'm thinking of downgrading and seeing what happens.

Hey guys,
I heard that FroYo differentiates the 3G and H icons on the notification bar.. but I have not seen mine change to H. How do I know if I have HSPA/HSDPA? I live in Orlando, Florida, so I would imagine we get good coverage here?
And also I see people put these crazy 3G speeds on their sigs of the speedtest.net application with like over 1MB DL speeds and such.. but the highest DL speed the application has recorded on my phone is around 600KB on 3G..
Any help?
H typically gains speeds of around 2-3Mbit i.e. around 2-300kb/s. So it sounds like you're still on normal 3G and an average connection at that. I only get H in a select few locations, most of the time I get the same speed as yourself.

Oh I see. Eh I just tested it twice on FroYo and got DL speeds of 17 and 43 kb/s wtf ?
I haven't seen the H icon yet on Froyo. Was using Kang-o-rama 0.7b1 before I installed Froyo courtesy of Paul @modaco. The H icon would display alot on the Kang-o-rama rom. At my desk my nexus would display H icon with Kang now it shows 3G with Froyo. I unfortunately didn't run any speedtests on it before I installed Froyo.
The speed I am getting now in an area that displayed H previously are: download .8Mbps and upload 1.2Mbps.
Would these be average 3G or H speeds?

I may be wrong but I thought on CM which is what Kang-o-rama is based off of, the 3G symbol is replaced with the H symbol and that is why you saw it where you would normally have 3G. Can someone else confirm this?
I don't know why people can't understand this, seriously. 3G=H. H is short for HSDPA Which is... 3G. What Cyanogen did was a visual mod nothing more. Which I hate now because we end up with post like this. There's no difference and if there is it may be the new radio.

H is enhanced 3G and H is faster than 3G and so 3G not equal to H. If H was displayed I expect to be able to get faster download speeds than if 3G was displayed and so I would prefer if H would be displayed when HSDPA available and 3G displayed when 3G available. I'm not sure if this can be the case.
3G = UMTS connectivity available (probably WCDMA).
H = HSDPA/HSUPA/HSPA+ link up.
H comes up only on custom builds (but some european builds reported to show H - not sure about the credibility of such reports), and H comes up only when data transfer is initiated.

Thanks Jack, I had noticed that behaviour on some builds alright but not yet on Froyo.
Whilst there is a difference between H and 3G the H icon will not show up on "official" builds.
It was just a graphical change made in some custom ROMs.
When your signal changes from 3G to H there will be no indication, but it will still happen.

Does CM make your reception better some how? I'm now getting H where I got 3g. I'm currently in Greece and I don't even think they have H here.

Cyanogenmod wiki:
Why do I see an 'H' for the network instead of '3G'?
"H" - HSDPA-mode
"3G" - UMTS-mode (slower)
The stock firmware shows "3G" when the phone is in either HSPDA or UMTS mode. The "H" differentiates it now.
so you understand why CM6 is showing you "H" instead of "3G"?

CM replaces the 3G icon with the H, there arent any improvements in the rom, you may have installed a new radio to cause a speed increase though

No, I just stumbled upon the answer and thought I'd post the answer in case someone else had that question. Which they have on a different thread.
I did notice better speed with CM6 RC2, Now I just flashed that Korean radio and I'm running RC3.
This much fun with a phone just isn't right.
Any one know how the i9000 roms show "H" for HSPDA but the captivate shows "3g"? I looked in the framework-res.apk but the connection images look the same. Will much appreciate an answer.
It is the modem that gives hsupa "H" support, not the ROM. Unless the ROM is packaged with the reoriented kernel and modem for the I9000 it does not support hsupa. Captivate does not support hsupa by default unless you are using a different modem than the stock modem. I could be wrong but after months of mods to my phone and experimenting with different ROM and kernel packages this is my understanding. Also be careful when flashing kernels and be sure to use only those made to use with Captivate or you will have auto rotation and button problems.

This is +1. H is just the 3g icon on the i9000. It has nothing to do with HSUPA. Even when HSDPA is enabled, the H is still there on the i9000 roms (try the i9000 rom with a captivate kernel and see what happens).
I like the H better, but I have no clue where to find it. Someone like DG, or someone who's torn the entire rom apart to find stuff, would know where it is.

Oddly enough the connection icons are the same on both roms. It must be controlled by something else that displays those icons.
On the i9000 the H icon only comes up when there is (a lot of?) data being sent otherwise the logo always shows up as 3G

This is not entirely true. HSUPA is 3.5g, 3g is 3g, and my phone switches between 2g, H, and 3g depending on my location and which the tower is supporting. My area supports all three and each shows up in my notification bar depending on which is being used. This is because I am running both an I9000 ROM and kernel with the JPM modem. I have all bandwidths enabled. It shows "H" even when no data is being transmitted.
Sent from my GT-I9000 using XDA App
ok, I'm going to try and clarify this, but the poster directly above me had it mostly right.
The i9000 ROM's are capable of showing G (GPRS), E (EDGE), 3G (3G), H (HSPA)... the reason our device will only show the first three and not H is because AT&T (and most US GSM carriers) have decided to lump 3G and HSPA in the same category. So when 3G is shown, you are likely already connected to an HSPA network, AT&T just considers them "close enough" to not need a different icon. This behavior can be modified, and I think DesignGears said it is a simple boolean fix in one of the XML files to allow both HSPA and 3G to be shown (I have not personally looked into this, but I see no reason why this wouldn't be so).
The European firmwares make the distinction because there are some places that are exclusively 3G and some places that are exclusively HSPA, and they can't be 100% certain where the phones are going to be sold, so they differentiate between the two. It has nothing to do with the fact that the icons are there, those are just pictures (they have no code).
Also, yes, this doesn't belong in development, General would likely be a better place.
When I had the froyo i9000 rom 2.2, Mine switched between H, 3g, and E, There were very noticable differences in speed when I was on H, 3g or E for that matter. when the H was on speed test would go up to 7mb and 3g like 1.7. hsupa and hsdpa is the same thing, u stands for upload and d stands for download. when you are on that and H is displayed u can get up to 7.2 mb at cap speed, but prob more like 3 mb to 6 mb on average. Those that are saying other wise maybe your wireless network hasnt been totally upgraded yet, I dont know but there are differences. The reason stock doesnt get it is because its not rolled out yet. The first thing to get true 3.5g or hsdpa is the air cards for computers, this came directly from a att general manager, then when systems are upgraded enough they will roll out ota's to the phones to beable to jump on 3.5 g U dont have to wait for it though u can do as some have said and use the modem for it.
HSDPA -> http://en.wikipedia.org/wiki/High-Speed_Downlink_Packet_Access
HSUPA -> http://en.wikipedia.org/wiki/High-Speed_Uplink_Packet_Access
HSPA (when you have both HSDPA and HSUPA) -> http://en.wikipedia.org/wiki/High_Speed_Packet_Access
HSPA+ (like T-Mobile is rolling out) -> http://en.wikipedia.org/wiki/Evolved_HSPA
W-CDMA/UMTS (what all of these are a part of) -> http://en.wikipedia.org/wiki/W-CDMA_(UMTS)
No need to argue further.
My fault on my first post.
However... if certain I9000 roms choose to display H even when connected to 3G... couldn't we just swap out .png files in framework-res??
Look inside with zip... and pull out the drawables folder. Inside are all the notification bar icons for data. Replace the H files with the files for 3G... and shouldn't that fix it?

no i9000 ROM displays H when connected to 3G. 3G and H are two different things.
