I'm wondering if upgrading my iPhone 5 from iOS6 to iOS7 will cause any loss of current functionality. I searched but could not find any thread on this. If someone who has done this could report the outcome I would really appreciate it.
Right now, I only have iTunes, Pandora (and bluetooth) functioning since changing from iPhone 4S to iPhone 5. This is all I really need and I don't want to lose these functions.
Thanks for any feedback!
