Bad idea man.
Never never go to a strangers home!
If the stranger say dunno what free thing right, sure got some
doubt. Especially when comes to free handphone ar. On the surface
say trade in, but actually is to sell off her handphone and keep
the new one.
If the guy say afew years don't have girlfriend liao, I don't
believe it man! Still dare to pet somemore 
Cheater; Player.
Meet one day and advance soo far.. Tsk tsk tsk.. the credibility is
lost.
Better ask your girl friend to break with this guy and stay clear
of him.
My 2 cents worth w/o GST.
