I am from India using an iPhone 4 CDMA version with Reliance network here. Currently the phone is running IOS 5.0.1, JB, CommCenter patched.

The problem is how can we confirm whether the changes done in carrier.pri is getting reflected or not. For example, i tried editing the MDN no. option in carrier.pri, updated the version in carrier.prl for the pri file, reboot, but then it still shows the old number if i go to Settings->Phone. So i think carrier.pri changes are not getting reflected. Am i missing something?
