Per TMobile, I need to JB my unlocked iPhone 4 & the wife's 3GS (5.1.1) to receive pictures via text.

Important: This fix only applies to unauthorized unlocks (Jailbreaking). Only use this solution if the customer has already unlocked their iPhone and installed the Cydia application on their own.
*
Add a new source and package to the Cydia application on the iPhone, by following these steps:
*
Open the Cydia application then select the Manage Tab at the bottom of the screen.
From the Manage Tab select Sources.
Select Edit at the top right hand corner then select Add in the top left corner.
Type the one of the following into the prompt:
http://beta.leimobile.com/repo
http://cydia.pushfix.info
Select Add Source.
This will add the new source to your list of Sources.
Tap the the source you added in step 4 then scroll and select the T-Mobile US MMS fix, T-Mobile MMS Fix or T-Mobile Internet Fix.
Select Install in the top right hand corner.
Then select Confirm in the top right corner.
Once it is done installing reboot the phone.
Important: If the device is using a tethered unlock, it must be reconnected to the computer it was unlock from. T-Mobile CANNOT offer support for unlocking an iPhone.
After the phone powers back on, from the main screen go to Settings, General, Network, Cellular Data Network.
Enter epc.tmobile.com into the APN field under MMS. The rest of the information for the MMSC, MMS Proxy, MMS Max Message Size, and MMS UA Prof URL should already be entered by the package we installed earlier.
At this point MMS should be functioning correctly on this iPhone. Test it by sending an mms to the phone from a test device.
This should only have to be installed the one time to fix this issue. There will be no need to continue to install this package again.
