i have a blackberry 8790 and the track pad on it has completely frozen. This has happened once before and i had to get the track pad completely replaced since it was due to water damage.
This time it seems unlikely to be water damage since i have not had near water, steam etc but the blackberry is completely frozen and not useable.
I have tried taking the sim card and battery out and left it for 12 hours but it still isn't working
Is there anything else i can do without having to take it to the store?

Its actually an 9780 not an 8790.
sorry
