I just used Ultrasn0w to unlock a phone with T-mobile. When going to edit the APN settings, I noticed the "Cellular Data Network" button went missing. Any Ideas how I might go about setting up data and MMS? Thanks, -Adam Here's the process I used. I tried unlockit.co.nz and got an APN error in safari, so I looked but there were no previous Profiles installed. Next I tried through cydia installing APN editor and that got an error and I had to remove the halfway installed app. Then I tried T-Mobile Prepaid APN carrier settings and the cellular data network tab still didn't show up in SETTINGS -> GENERAL -> NETWORK. The phone does work with call and text...just no data.
