i have a german ja5 lite rom from tom33.
have noticed that this keyboard-popup only appears since the new WidgetPlus (JB1)! maybe there is a command to the phonebook so the keyboard pops up.
have noticed this problem also in the original JB1 version so i think it the problem must be the new WidgetPlus.
but have someone a working WidgetPlus version JA5 or JA1 with ability to add widgets?
Because of your encountering, I had re-flashed my Omnia2 with Khuanchai i8000KC21889A5 Lite.
I had installed my WidgetPlus JB1 version immediately after complete booted.
When I presses the phonebook softkey I did not saw the keyboard appears instantly.
This is even with Khuanchai default "HKCU\ControlPanel\SIP" "TurnOffAutoDeploy" set to 0.
Maybe it was because I previously flashed my Omnia2 with secany JB1 ROM, Eboot, Phone & PDA 3parts that make the trick.
You should try to flashed the same 3 ROM parts like what I did to see if it helps.
