I know the answer to this is to head to the genius bar, but my 4s continues to crash when sending MMS pics and during other random events. The battery is also draining every night. I thought it was due to lack of memory, so I wiped all data and restored the phone yesterday. When I went to bed last night the battery was at 40%, 7 hours later it was completely dead again, and had to be charged. Am I missing something here?
