Received new phone on the 14th. Restored from backup. The at random times, phone would turn itself off and I couldn't get it started again with out doing a hard reset. So yesterday I decided to restore to factory defaults and manually setup the device and not do a restore. It still continues to crash at random times. Under diagnostic and usage, there are tons of crash logs and low memory logs. Anyone else having this experience? Should I just take it to the apple store and see if I can get a replacement?
