Has anyone with an iPhone 5 had this happen? This occurred on my 4 last July. I went from 1.4 gb available space to 523 mb overnight with no apparent reason for it. The Verizon tech found nothing and patched me to an Apple tech, who also found no cause for it. The only thing I had done was update 2 apps. One went from 48 mb to 122 mb in app size. So that was a small part. After talking with Verizon again, they offered to let me upgrade 5 months early to the 5. Since I don't know what caused that to occur, I'm concerned it may happen again. Any thoughts out there?
