So I'm interested in changing out my 7290's faceplate for a new one, but after perusing the forums and BlackBerryFAQ, I couldn't find a guide for how to break it apart. Assuming that the faceplate I buy comes with instructions, I have a couple questions to ask.

1. How difficult is it to disassemble a 7290? I don't have much experience with handling sensitive electronic parts, but have a good grasp of common sense and practical know-how.

Any tips on disassemble? Besides gloves, lens cloths and compressed air, anything else I should focus on? Is this model sensitive enough that I run the risk of breaking it with a slip of the hand?

2. I know about promobility, but I'm thinking of buying a colored faceplate from eBay. Is the plastic and paint comparable on these models (shipped from HK) to the original make? Would you deter me from buying from these sellers? Any personal experiences would be great.

Thanks! Any help would be greatly appreciated.

You'll need a Torx T-6 style screwdriver bit to open the Blackberry 7290 (and, presumably, anything else in the 72XX series). Basically I have not found any step by step pictures, but it seems you just remove all T-6 screws..But I do not have this phone so I cannot verify that. Sorry there is just limited info on this.
As far as handling anything coming out of the device..just be careful with each piece, and try not to touch it no more than you have to.
Good Luck
