Doesn't 3 have shocking reception? Here in australia they are a joke. The only way I countered this weakness was to install jpe modem. Now signals a bit better than jpy but battery on standby is exceptional.

Yes i heard very shocking. And the best for 3g as they own most of 3g but its not that fast. How do i check jpy? And move to jpe . I.am a noob lol

Put it on root of sd card.
Go into recovery
Choose install from sd card
Install jpe or whatever modem you choose.
Thank you friend

i'm with 3 in aus as well, i try to flash jpe and i don't see it get better, it's pretty much same as jpy.... is this 3 fault? or we have to try other modem like the stock jp3? any idea?
If you are using Telstra or 850mhz band / i9000T try the UGJL2 modem from here

[Q] help me with fixing this~ unsual

T-mobile galaxy tab.
band: P1000XXJMA
kernel: 2.6.32.9 [email protected] #1
build: FROYO.XWJMI.Roto-JMI-v2
my current provider is Mobilicity which uses AWS network(HSDPA 1700/2100). Tab must work well on this provider since T-mobile galaxy vibrant is working so nicely with Mobilicity.
but the problem is even if i put the SIM card in the tab, the tab won't find any network. I rooted and unlocked properly.
help me~ what is wrong??

Have some patience, that was just an hour... Anyway, did you flash a modem? Because otherwise it's not really going to work.

which modem should i flash to? is there any good rom that works with my provider??
No clue. Since you say TMobile tab works well, i'd suggest that one. However i'm not an expert by any mean, so you might want to look around/wait for more answers.

The T-Mobile US modem is the only modem known to support 1700/2100 AWS, so if you want 3G it's your only choice!

Look for the standard TMO 3G modem in Roto's modem switcher thread in the dev section.

Looking to sell my old phone to an optus user, it has JL2 installed which worked ok for Telstra but Optus seems to have a weak signal. I have a RomKitchen Rom (Android 2.3.5) installed. What is a good modem for Optus and where can I download it?

[Q] strange problem of only one sim working.

I have a galaxy tab p1000.
Firmware-2.2 (stock version)
Baseband- p1000DDJM2
Kernal- 2.6.32.9 [email protected] #
Build no-Froyo.DDJM8
Its network unlock as I bought it from market and I have used
Different sims..
Bt recently a new problem has started.. Only bsnl (india) sim works
On it.. Other sims dont get signal..
For eg. If i have inserted vodafone sim, It shows vodafone sim bt i
Dont get any network tower. Instead I get a crosscircle.
I checked my sim lock by dialing some code I gt here(*#7.....#)(dnt remember)
it shows all of them off..that means it not locked.
So I cant understand why my other sims have stoped working suddenly.
Plzzz help.
it seems no1have a solution to this problem yet..

Try flash a different modem. JPZ for example.

Get JPZ
I can't confirm that Gingerbread modem works in Froyo.
But I am pretty sure it can.
You need Odin v1.7
and need to put the modem.bin in the "PHONE" part of Odin and DON'T tick "re-partition"
I would recommend upgrading your tab to at least GB though when you are up to it.
The guide and files are in my signature.

The bandwidth of your JVU must be compatible with the spanish regional networks
