.....the iPhone normally does it's system updates at night. Nothing sneaky going on here. Extremely unlikely your phone has been hacked. How long have you had the phone ??
AT&T swears that my phone can't be hacked but I am almost over my data plane because almost every night at around 11:45 my phone is using a bunch of data while I sleep.
Can anyone explain this, and is anyone having the same problem? Thanks
