Ladies and gentleman, I need to order a screen (glass only) for all of my iPhones. First gen, 3G and 3GS. I see many vendors online all with similar pricing structures. Curious if anyone has used any of these shops and who might come regarded the best? Any suggestions from people who have first hand experience with any of these shops very much appreciated. Also, do I dare get suckered into the "extra" tools like the screen removal suction cup, case opener, screw driver and adhesive strips? TIA. ~Tommy PS - yes I know it's time for me to start using bumpers!
