iPhone 5 keeps freezing. Mid text mid anything. Very annoying. I am not eligible for a upgrade until feb. Today I have restarted my phone 3 times. The last time I tried doing that I couldn't get my phone back on. It stayed on the white screen for at least 10-15 mins. My phone is the ONLY way for anyone to contact me. I have kids and it is very important my phone work for various reasons...doctors...schools everything. I'm getting very annoyed that I'm paying for a phone that is malfunctioning I need to know how to fix this without a hard reset.
