Recommendations for new phone

I current have a Sony Ericsson K750i which has given me the folling problems:

1) Joystick locks up every now and then
2) Battery becomes loose and the phone switches itself off.

I will be upgrading this month but don't know what phone to get. Any suggestions? I'm not sure if I would want another SE as they have only ever given me problems, so maybe a new Nokia?

Thanks!

 

What features are you looking for in a new phone?

 

It needs to have a good txting facility, as well as an organiser. These are the main two features that i need, everything else like a camera, games, wap etc all are nice, but not as important.

 

Have a look at the

Nokia 6086
SE W850I
Nokia 6800
I love my Nokia 6131 but it is not what you are really looking for.
Nokia 7380

I will list some more later ;-)
