well it might not have been from the keyboard, but the day after i installed it my phone started to freeze up alot more often, like 2 or 3 times a day. it was odd and this might not make sense. basically, everytime I clicked something on my start menu it would duplicate my start menu, it got to 7 rows of start menu icons, where i would have to scroll down to get to the bottom of them. those were the only things i really noticed though...and remember, im on windows mobile 6, so it might not have any problems with wm5
