Do not allow iTunes update your carrier settings
EDGE / GPRS settings disappeared.
Since a few days, iTunes has been asking to update my carrier settings on my iPhone. I originally kept clicking cancel but yesterday I clicked yes. The installation took a second and iTunes said it was done successfully.
The iPhone appeared fine, but it lost the EDGE settings -EDGE settings disappeared (it obviously does not allow Edge editing with my provider).
If that happens to you, go to http://hackint0sh.org/forum/showthread.php?t=18814to see how you can fix it.
To remove that message for T-Mobile US
I also had the annoying iTunes message upon plugging in my iPhone
"itunes needs to check for a carrier update" or something, of course I always hit "no" just in case it wants to set it back to AT&T.
So, on the iPhone, I opened up Cydia, hit "Sections" then "All Packages", scrolled to t-mobile, and installed the "T-Mobile US Carrier", then restarted the phone (hold sleep/wake button, powered off, then powered back on with same button).
No more annoying message. Thanks Open-source geeks! :):pie::cool:
It sounds like there are other Cydia packages for other carriers too.
