How to force enable the iPhone Carrier / Network Selection Menu

[h_2_o]

r333 the problem i was having is even with ultrasn0w installed after a reboot the carrier menu would go away. with the patch it works.

My problem now is that the patch is for 4.0.1. I need one for 4.0.

After adding the Override I am not able to receive or send MMS pictures or anything. I have a Iphone 4 with 4.1

I made the changes <key>allowmmsediting... <key>overridecarrier.... (i changed the permissions of the carrier.plist to read read read but i'm not sure if that was necessary) then went to General->Reset->Reset Network Settings. iPhone restarted with all the changes made without losing MMS. Running 4.2.1. tried it on 4.3.3 and did not work, will keep trying for a different solution for 4.3.3. REMEMBER, BACK UP YOUR IPHONE BEFORE RESETTING ANYTHING JUST INCASE.
