Whats wrong with a jailbroken one Ekona?
Nothing as such, I'm just thinking along the lines of something like a keylogger which is impossible to do on a non-broken iPhone, whereas you can put whatever you want on a jailbroken one with relative ease. Access to FB and everything else is easy to get via social engineering or if you use the same passwords, but the telephone number thing? That's the puzzler here, and unless she does have a mate in CPW who is passing on the details then there has to be something on the phone.
...or not, as with a way of accessing the PC/Mac remotely you could view the iPhone's telephone number on screen when connected to iTunes. That's all I've got really, not much help I know.
Well every snippet of info is helpfull as it builds up to a bigger picture.
Mine keeps sticking the keyboard up whilst it's in locked at the moment.
I have to do a hard reset about 4 times a day which is really annoying!
