regardin the touch pad probs

i use to have the same prob.
the center touchsensitive button went dead while the other 2 worked.

anyhow its a common prob, i went to a service shop and got it changed.
sadly i had to pay for it, as my warranty was only available in Australia where i bought the phone from.

ones keypad changed - no more prob.

the only prob i still have is the phone keeps hanging every now n then, it automatically restarts n ****!
bladde annoying if u ask me!

wonder why SE cudnt solve all this crap supposedly in making some top end phone!
