Hello. I'm looking for the most stable rom which can give perfect works in the 3g network. Now I using f1 rom but the speed of 3g is very poor and not stable.

Hi there,
at first, you should decide, which android version you want to use.. if you're looking for most stable, e.g. most tested and proofed stable over time, I'd personally recommend darky's rom http://www.darkyrom.com/community/index.php?threads/darkyrom-v10-4-2-xwjw1.6577/ v10.4.2., which is based on latest Gingerbread Samsung sources. (a good guide for flashing, coming from different ROMs, is included.)
As for a rock solid Kernel, I'd go for the Speedmod-Kernel: http://forum.xda-developers.com/showthread.php?t=1044519
To get the most out of your 3g network, you should then flash different modems to test which one serves best in your region. Modems are tuned to different regions and carriers. Here is a comprehensive list: http://forum.xda-developers.com/showthread.php?p=9579987#post9579987
My Personal analysis : It seems that the the top rated modems are the ones released in built up areas/countries/regions, and i designed to use more battery to give the best results especially when it comes to GPS Lock & Accuracy, Network, Speeds & Coverage. This does make sense, so if your in a built up area and use a modem designed for a less built up area which requires less power your not going to achieve goods results on paper, but if you use a modem designed for a built up area in a area that requires less, then your results are going to be sky high BUT might be to high and in turn drains more battery power than needed. So yes Modem's are clever little things, you have to find the right balance for your area, network, coverage, GPS and so on.
JPP is considered the TOP modem preference (See points below) BUT its uses alot of power to get those results.

Most people do notice that devices seem to get more responsive, after rooting. But evidence is rather anecdotal as it is hard to judge performance like that (screens changing quicker etc).
In my case, SpeedTest, on WiFi, went from 7Mbps to 18Mbps ! As a result, one could reckon that anything related to networking, should get a pretty good boost! And overall the device does seems to be faster across most of usual activities.
I am running BakedGoods distro .
When I switched from stock to CM I instantly noticed the phone was much faster in lauching apps and even moving through menus. Obviously, the RAM part is the key to this debate.

That characteristic is configurable in the file /system/build.prop.
Typically, community firmware is SLOWER than stock as a result of inclusion of a whole bunch of experimental/broken/useless crap. Most of the reports of being faster after rooting are the placebo effect.

This is true regarding to stability. But overall performance is increased with custom roms. Numbers do not lie, check the benchmarks.
I still don't see why Wifi speed would benefit from custom ROMs.
The only speed enhancement I 'see' is when I use spareparts to increase the window animations. Other than that...I love all the addons that I can use being Rooted!

Well, all roms are based off of ERE36B which has an updated radio (4.04.00.03_2). ERE27 is what all stock n1s are running and has a radio version of 4.03.00.21_2.
One must wonder if during the arbitrary number increase, more functionality was added (would be nice to fully utilize the 802.11n chipset built into the n1, yeah?)...

Interesting point... I wasn't aware that the radio update also controlled the Wifi on our phones.
Nexus one kernel
I have a question about flashing kernel, i was about to install kernel 2.6.32 on my nexus one,but i already installed the Cyanogenmod 5.0.4.1, and i notice my kernel version is (2.6.33-cyanogenmod).So does that mean i already have an updated version of 2.6.32 and there's no need for me to install the 2.6.32?
So I had twingerbread on my phone for quite a while, really good battery life and amazing, i MEAN AMAZING signal, nothing less then 4 bars in my house (stock or any other rom 2-3) But I want to try something new, so i tried phoenix 7.0, and I really like the design and everything but my bars are in the range of 1-3 most of the time. What should I go with....?
This is REALLY your own choice. If you would like, you can always try putting the modem that Twingerbread is using on to your Phoenix phone (if they are using the same version of Android).
That should theoretically give you the best of both worlds (as far as "style" and signal strength goes).
Both of these ROM's use the same modem (jk4), so it's odd that they would have drastically different signal strength.
Check that the rom maker didn't change the signal images to artificially boost signal.

yea that may be the one where there is no graphic for 2-3 bars. basically the phone will always say 4 bars unless it is down to one bar or no service. read the first post i read it in one if the threads. the dev did that because he doesnt really care to know if it is 2 bars as long as the phone is working.
Hi. I just wonder about this.
Many times, when a new firmware comes out, after 2-3 days there are custom roms based on it, with tweaks (edited build.prop for example) and other speed mods.
Do they really improve speed? I mean seriously, if someone tests the 3-4 most known stable custom roms, based on same android version, and with the same kernel, also with the same apps on it, will be any noticeable difference in speed?
I see other devs releasing a rom after 3 days, and I can't explain what kind of tweaks could give more speed being stable at the same time.
Maybe custom roms are just modded/themed stock roms, and when there's a speed differenve it's because of the kernel inside.
Just being curious about that (also could make the choice of the rom itself easier...)
Any opinion? From your experience at least.

A mixture of both .

definately a mixture of both. They both make huge improvments over stock. in my opinion anyway
probaby karnel or speed
some costum rome improve your phone speed or karnel speed. especially visuality.

I don't need to improve my phone's karnel speed, it gets enough girls as it is.
However in my experience speed improvement and the smoothness that comes with it are mainly the process of the kernel as that controls the interaction between android and the hardware, where most performance bottlenecks happen. The ROM itself adds functionality, appearence and most important of all...stability.
At least so it appears to me.

I partially agree. I mean, if we assume stock roms are stable, custom roms can;t be more stable.
So, they provide some speed, maybe because there are not so many system apps inside, and mostly they provide some nice mods (visual and functional).
Hey, I'm using Phoenix unleashed js8 with speed mod and baseband version i9000ugjk4. When I dial it' ringing and after few seconds them volume drops and become even lower then the original in call volume that isn't so high any way. It started bothering me when I first talked in a crowded place and didn't hear good.
I heard something about modems but didn't really understand it.
I'm living in Israel and my carrier supports 850/2100 UMTS (No GSM for 2g bands) and that's why I bought the cappy.
I have two questions:
1. How can I increase the volume of the in call volume?
2. How can I know if my phone is using both 850 and 2100 bands?
And a little question on the way..
How much time will it take until the roms and kernels of GB will be as stable and fast as the froyo roms?
Thank in advance, Elad!
anyone? :S

1. I've noticed the same thing with call volume. I often have to switch to speakerphone to hear in crowded locations. I know that's not really a solution, but it's a temporary workaround for me. I'm not sure if there is any actual way to increase in-call volume.
As for stability and speed of GB ROMs: I recently made the upgrade (was running JS8-base OCed to 1.4GHz) to Mosaic II and can tell you that the speed and responsiveness of my Captivate has drastically increased (despite now only being at stock 1GHz). I think now is a good time to make the switch.
Try a kb1 kernel and modem, that has the support for the audience chip that all I9000 kernel/modems don't have, because it's a different chip in the I9000 than it is with the captivate...

Don't you have bugs and FC with your apps? what kernel do you use?

What is a kb1 kernel? the kernel I'm using now isn't for i897?
It is but it was ported and reoriented from the I9000 to work for the captivate. That was done because att drags there asses with updates, froyo came out in europe and canada months before att.
Kb1 is at&t's version it has the drivers for the audience chip I mentioned. Look in the dev section for kernels, it'll say kb1 next to it there should be a couple ... You will also need to flash a modem to match or you will have major sound issues.
here are 2 kernels for kb1:http://forum.xda-developers.com/showthread.php?t=988805
and:http://forum.xda-developers.com/showthread.php?t=989298
now look in this thread it has a modem for the I897(kb1) http://forum.xda-developers.com/showthread.php?t=989298
once you have a kernel and the modem flashed your sound quality should improve...
Oh and as far as gb goes it's the same thing I mentioned about froyo, not ever gonna be released by att, but it came out for the I9000 last month, and the reoriented kernels for it are pretty stable. the roms based on those kernels are fairly stable as well, my personal fave is mosaic but I'm biassed because I'm part of the team
haha, Phoenix is the best, I enjoy every second of using this rom!
I think I will stay with this modem and kernel because it really give me great perfomence. I will live with this volume
As for the GB, I think I will give it more time and wait for the kernels to have lag fix and to be more stable. My next phone won't be AT&T's, that's for sure.
Thank you both I appreciate your help!
Using Krexus ROM with latest ex kernel, radio is currently 36R but i've gotten the same results with other radios and ROM+kernel combos. What could cause Cell Standby to use so much battery? Signal isn't the greatest where I work and at home (using AT&T), but even so does this seem right?
Check out them screenshots.

answer to your question is your signal quality. people that have great battery life usually have a great quality signal. people that get terrible battery life usually have a terrible quality signal.
