My daughter's iPhone 4 (16 gb) just notified her that her phone is almost full. Since she is at the beach for the week, and can't back it up on her computer, I told her to delete pictures that she knows have already been backed up. Is that what she should do? Any other advice? The good news is that she is getting a brand new iPhone 5 32gb, on the day she returns from her trip. We just have to limp along until Sunday.
