Omnia and WM 6.5 ?

[-nVIDIA- (OC)]

Hey guys, im kinda new here and need help.
Well ive got an Samsung Omnia and only have probs. Like if someone calls me nothing hapens. Next thing is, when i charge my battery, the symbol does not appear so i dont know if it is charging and so on. So i only got probs with that thing.. Kinda pisses me off cuz i have to soft reset it all the time -.-

My Omnia Version is:
PDA: i900XGIC3/BHIC2
Telefon: i900XXIB2
I am using Windows Mobile 6.1 Pro. (Build 20270.1.3.1)

Does it make sense to upgrade to WM 6.5 ? If yes, what diffrence does it make ?

I need help big time. If the problems dont stop, then i have no other choice to sell it.

Does anyone have any tipps or anything for me ? Please its really important.
Oh yeah, ive been reading something with kitchens ? What the hell is an kitchen ? xD

Thx guys
