Real solution to ALL N900 problems is to buy an Android Phone with physical keyboard. I did it and never needed to thoroughly read the android forum.
Don´t try to get juice out of a stone.
I will give it a try again when there is a mature version of Maemo o Meego.
Sincerelly do not waste your money and time. Those should be use for fun! Instead reading how to fix what shoud be well done from scratch.
Nokia made to many mistakes with phone paid with our pockets, the glory times of the Nokia 6600 or Nokia N95 is long gone.
Move forward
No hard feelings
