I restored my phone to IOS 7 beta 2 but the carrier settings version (Sunrise CH) is 14.5 and it does not allow LTE...only 3G. I tried to update but it also replaced the carrier settings. IOS 6 version is 14.1 and it allows LTE. Is there any way to stick with version 14.1? I restored my Iphone 5 to IOS 6 and itunes did say "download and update carrier settings" but I have no clue where in my macbookpro (10.9 version) has been downloaded. I figured that if I find the file I can use it with IOS 7. I did call provider support and they said that they will release an carrier update once IOS 7 is released 
Any ideas?
