SOMEBODY HELP PLEASE my iPhone 6 Plus is stuck on edge on the Telstra network i purchased an iPhone 6 Plus 128gb a few weeks ago from apple and when i received it i restored through iTunes (Latest version) the old backup of my iPhone 5 32gb (which was running ios 7).. after backup had completed my iPhone 6 is now stuck on EDGE Data!!and when im in the city i get 4g sometimes but i cant live without 3g data.. i usually get 3g all the time.. i tried resetting network settings, and all settings, hard reset, reboot without sim installed. and nothing helped, so i decided too restore the iPhone too factory settings (ios 8.1) and the problem was fixed !! so i now know there is something wrong with my backup, but i can not have my iPhone without all my past messages/photos.. so i then tried fixing the issue by restoring the backup back onto the iPhone 6 and backing up through icloud .. i purchased 200gb icloud data and i backed it up.. it tool about 3 days..once backup was complete i restored the iPhone too factory setting once again and restored my icloud backup,, AND STILL THE PROBLEM PERSISTS@!!!!!!!!! is there something i can do too modify the backup or settings or something and fix the backup? its like its corrupted or something. it is also now jailbroken could there be a tweak or something that could fix it?
