Yes Rogers is most likely right as that does sound very much like water damage. There isnt much you can do as water damage repair involves expensive equipment. Your best bet is to send it off for repair. If you google cell phone repair there will be many eager merchants to help you. Also fixya does provide a vast directory of repair specialists found here.

good luck :)

This is controlled in your settings menu under 'Fixed Dial'. (or similar command). You will need to change this setting.

I do not have a copy of the user guide for your phone but for most phones these are the directions:

When you turn on fixed dialing, you
can call only numbers stored in the
fixed dial list.
Turn fixed dialing on or off:
- > Settings > Security > Fixed Dial
Use the fixed dial list:
- > Settings > Tools > Dialing Services
> Fixed Dial
