Got my 3rd replacement 8800 today and noticed that is was a pretty solid build (finally). however i wanted to play it safe and save my self the hassle in the future and decided to use the electric tape method.

when disassembling i noticed the top of the chrome sides were hard to remove. i carefully lifted it up and discovered that blackberry used extremely sticky clear double sided tape! this seemed to have cure most of the squeeking problem that the sides were having. however they only used it on the top, so i carefully placed some more double sides tape on the rest of the inside of each chrome side. and all i can say is what a difference. feels really solid compared to all the other 2 8800 i had. so it seems blackberry knows that the housing is squeeky and attempted to fix it.
