Boo!
Boo I say, bad form!
On a serious note its a really sickening feeling to put your hand to your pocket and find something missing. It seems that after I spoke to my girlfriend when I was on the bus someone saw the phone and decided to follow me.
I was waiting at a busy bus stop after that for a night bus and people just bang into you so after a while you don't pay attention, so thats when it was taken.
I have called Tmobile and got it blocked, I also phoned up the police to get a crime reference but then I discovered that section of the house insurance has a £125 excess and the phones only worth £120
