Ok so I dropped my phone face first on asphalt due to Apples slippery sides. Never mind the fact that I hate phone cases but I've checked out the glass + digitizer replacements and have a few questions. 1. I've seen some through Amazon.com for ~$30 and some specific sites that specialize in repair sell them for $~60.. Any differences? do I get what I pay for? 2. Is it fairly easy to take apart the phone? I'm pretty technically inclined I've taken apart pda's to overclock em, modded PC's back in the day (circa G5 Mac) 3. Does it work as good as the original? any issues with finger taps or anything?
