If you haven't tried yet, move the .apk to data/apps, but don't "install". Instead use Root Explorer to change the permissions to RW-R-R..
not sure it will work for you but I think that's what I did to make either Handcent or Facebook finally work for me...
Be sure and reboot after you finish with Root Explorer..

OK to after you moved the apk into data/apps and changed permissions, you rebooted. Did u install handcent after the reboot?

I don't think I had to, since moving it into data/apps and rebooting basically is the install anyway....
Changing the permissions is the most important..
Hope that works for you..
