I have seen a few posts about various fixes for the inability to save Edge settings (it bounces me back to the springboard).

Thing is, using Fugu, I cannot see the 'unknowncarrier.plist' file, only the 'ATT_US.plist' and the others in the 'core telephony/support' folder.

I tried using an application called 'Edge settings fix' but it appears to have done nothing.

Any help?
