can facebook be hacked on an iphone?
Hi - this morning, i was typing an SMS, my battery was on full (98%), but mid message, my phone seemed to switch itself on again (without actually switching off!) it displayed the apple screen that you see when you turn your phone on. And then when i tried to access facebook, it said that my 'facebook login expired', yesterday i got a message off someone elses facebook account, but it wasnt them, someone else had logged on trying to stir up some trouble unfortunately, and it said on the chat that i had recieved the message 'from mobile', so when my iphone did this to me this morning, it made me think someoen is possibly now trying to access my facebook through my iphone?!
Is this possible?!
any advice would be much appreciated.
Thanks x
