Same issue. I have done reset network settings multiple times. Deleted files, left the iphone off, dusted off the SIM card. Also now my phone slows down to a grinding halt, then, if i pressed buttons or performed gestures while frozen, it does than all at once after a long delay, then freezes again. I am only using half my memory. So its not storage issues.
