eBuddy 1.5 does not work because it needs a class from JSR-234:
javax.microedition.amms.control.ImageFormatControl

Not sure what is wrong with mig33 (I just ran the app until you
have to login etc).

I installed and ran the Facebook chat app. I am not an avid
Facebook user, and I am afraid I do not entirely understand your
problem. Perhaps a screenshot would help.

However, I am aware that the built-in virtual keyboard is pretty
broken (all keys are aligned to the left side of the screen). The
idea is to use the Maemo native virtual keyboard, but it is a bit
tricky to implement without any Qt4 text input widgets that would
trigger it automatically.

On Android, I drew a virtual software input panel button at the
bottom with which the users could pop up the native virtual
keyboard. I am going to try to achieve the same with Maemo.

Cheers,
Davy
