Malware on iPhone4 running ios5?
Just had mobile bill for son's iPhone. He's exceeded his data usage and landed a bill for £158, but I'm not sure it's his fault.
Having analysed the usage, I'm seeing the same pattern every night around 10pm (when I know he's in bed and asleep) of load of 1Meg and 0.5Meg GPRS records. It feels like a worm?
He's turned data off on his phone, so there's zero usage, but can anyone suggest what to use to scan this phone to check it... and how to prevent it future please?
