iOS 4 / 4.0.1 T-Mobile iPhone MMS Settings

After Jailbreaking and Unlocking it's possible that the MMS function will not work. I used these settings to get my iPhone 3g iOS 4.0.1 working in T-Mobile.

• Go to Settings > General > Network > Cellular Data Network
• Input the following: 

APN: wap.voicestream.com

Username:

Password:

MMSC: 216.155.174.84/servlets/mms

MMS Proxy: 216.155.165.50:8080

• Exit, Reboot, and Done! 

I used these settings yesterday and they work. Let me know how if it works or doesn't work for you. Good luck!
