Disable GPRS or MMS
When you absolutely dont want to use grps or mms, f.e. because it costs too much etc you can use this tweak to disable it: 1) Open registry editor
2) Go to the key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ConnMgr\Providers\ {7C4B7A38-5FF7-4bc1-80F6-5DA7870BB1AA}\Connections \IDEAS Internet (GPRS)\Enabled
3) Edit the key 'Enabled' by double-tapping or otherwise.
4) Change its DWORD Data from '1' to '0'.
5) Go to the key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ConnMgr\Providers\ {7C4B7A38-5FF7-4bc1-80F6-5DA7870BB1AA}\Connections \IDEAS WAP (GPRS)\Enabled
6) Edit the key 'Enabled' by double-tapping or otherwise.
7) Change its DWORD Data from '1' to '0'.
Soft-reset.
