Hi all I bought a second-hand Treo600 the other day. It worked fine for a few days and I was very happy.

Suddenly one morning, the bottom row buttons ceased to function!! The shift,alt,zero,spacebar,menu,enter and backspace buttons don't work anymore. However the home button still works.

My phone is effectively disabled, I don't know what to do... I am desperate. Is this a known issue? Could it be a software or a hardware issue? Please help me

best regards
