I just got a new replacement iPhone 4 and downloaded the new iOS7. I did the restoring over iTunes and all that jazz, but now my phone has lost cell phone reception and I cannot make or receive calls. I can still connect to WiFi and use iMessage and all other applications. My GMail is still coming into my OLD iPhone 4 that I am no longer using instead of my new one. I am in the army and have a unit to run so this is very frustrating. PLEASE HELP!
