galaxy s gone mad and has a mind of its own

[Guest sph90457xp]

Hi

I have 2 issues with my galaxy s i 9000.

1) you can only use the o(9) key if you turn the phone sideways.

2) the phone twitches alot and the grey bar at the top of the screen slides down the screen on its own accord and then randomly selects apps or different options on apps you are using. It also auto zooms in and out without you touching it like it has a virus or something. Reboots dont appear to fix it - any ideas ?

Firmware 2,2,1

Model GT-I9000

Froyo.xxjpy

kernel2.6.32.9

please help cus i feel like smashing it to bits..
