No tmobile us bundle 4.2.1

[Ian3head]

Hello I have an iPhone 3G on 4.2.1 unlocked with ultrasn0w on the iPad baseband... I beleave I jailbroke it with redsn0w 0.9.6 b4.. And I live in the US.

First of all I have many tmobile bundles but none exist for tmobile us? I've looked through the whole device with winscp & ifile. No dice.

Basically my goal is to somehow.. Easily add a us bundle, and then hopefully once located change the "T-Mobile" text to the tmobile . Png logo which I already have... Really I'm more concerned about getting the tmobile logo to work.. And I've already tried copying the correct file names ex: "FSO_CARRIER_T-mobile.png" ect to unknown.bundle but no dice...

I really hope apple is not signing carrier logos now.. Can somone help?

Oh yeah another reason for this is to fix mms too. The mms fix 4.0 package through cydia doesnt work for me... I'm currently using "epc.cmobile.com" for my data.

i believe its epc.tmobile.com not cmobile.com. also have you patch your commcenter?

For an iPhone 3 or 3GS you don't need the comm center patch because the patch is mainly for the iPhone 4.. Once you jailbreak your phone and then run ultrasn0w you want to install tmobile 4.0 mms fix from the repo pushfix.
Reboot, and then go to settings/general/network/mobile data network. Then input these settings
APN internet2.voicestream.com
Username
Password

Mms
APN Epc.tmobile.com
Username
Password
MMSC http://mms.eng.msg.t-mobile.com/mms/wapenc
Mms max message size
Mms UA Prof URL

Once you put these settings in make sure you reboot your phone and before you put these settings in make sure you have your t-mobile sim card installed. Once you reboot make sure your 3G is off.

Troubleshooting :
If you install the mms 4.0 fix and you don't see the mobile data network option just pop out your sim card and reinsert it and you should see the tab pop up and continue..

Since your on 4.2.1 if you haven't activated with a legit sim(AT&T) you should create a custom ipsw that isnt hactivated and restore to that custom firmware without your tmobile card but with an AT&T card installed. It doesn't matter that the card is not active iTunes only needs the at&t card to activate your phone. Once the phone is activated set the phone up as a new phone . After you activate your phone install ultrasn0w and the previous steps I outlined earlier in my post. The purpose of this is to activate legit push notifications when used with another carrier such as tmobile..

If when you input the above apns and still have no mms or internet try these instead
Data
Epc.tmobile.com

Mms
Wap.voicestream.com

** Make sure you reboot twice anytime you change APNs ..
Hope this helps.. Post any issues that you run into..I'll try to respond in a timely manner..
