Triminion got it right. I would NOT glue it, or you'll never get it off if ou want it done correct.
Search YouTube first, then get the parts. I did the same on my iPad2, 1 month after I got it!
Got the glass, tape and Metal bezel from gadgetfix on eBay. . .no affiliation, but that's where I got them.
The tape was a little shy, so I'd get two sets or buy my own. . . it's REALLY thin double sided 3m tape.
Glad I got the bezel- mine got ruined during removal.
Heat gun was priceless (thanks MGM).
Ran my scraper (putty knife) on the grinder to bring it down thinner.
Cost about $60 plus my labor 1 hour. The hardest part was finding the gorilla glass. I'm not entirely sure I got it, BUT, it doesn't seem flimsy like some others I've seen described, and the packaging looks right. Of course, anything from China does these days.
Bottom line. . . I'd do it again if I had to. I'm on the iPad right now. . .
Ken, truth be told, I cringed when my wife got me an iPod Touch. I thought,"What for?" I had to upgrade to the 32mb version for more memory. It's invaluable to run music through the PA to practice. Suffice to say, I said the same when she got me the iPad2. Glad I have a wireless router in the house. . . I'm never on my computer anymore.
Now, with my latest project building PA and Bass cabs, I can use the touch to run pink noise through the speakers and analyze it with my RTA app on the iPad so I can flatten the speakers with an eq, and notch feedback easily from the monitors on stage.
I'm now scoping out the new Mackie DL1608, not for the amount of channels, bit for the size and power. All I'll need is that direct to an amp (no eq needed). Just gotta sell another Uke to fund it!
