Bit of help needed (for all you brainiacs out there) Sister's got an iphone4. All of a sudden and without warning all incoming calls are coming through as blocked, She can ring out OK but not receive calls. Nothing has been jailbroken or anything.

EDIT: Tried phoning her from my mobile and as I am a contact it came up OK

It just means that whoever is calling has withheld their number.

It doesn't mean the call is actually being blocked. She will still be able to answer these calls.

I tried to tell her that (Googled not long ater I posted and found it was common) She thought the phone was faulty though and took it back up to the 3 store................ Needless to say she got told there wasn't a problem

Is she from Essex?

LOL Nope but she is blonde

I was convinced that this was a joke...

I wish it was a joke but was 100% genuine trust me
