Did you break your iPhone screen while in Vegas?? I bet you did, because we've all done something like that before.
Head off strip to Wireless Phone Doctors off Rainbow and 215 in the Southwest. They're quick, knowledgeable, and efficient.
I brought my work iPhone 5 in for a repair - the screen had popped off after a small impact and was not responsive any longer.
He was able to show me that my battery had expanded (physically gotten bigger) and that put pressure on the screen, which lead to the small impact pushing the screen out.
Display and digitizer fix and a new battery for around $100.00 and I was good in 15 mins (fully tested and looked/functioned like brand new).
A big plus for me is that since it is a corporate phone I needed two things:
1) Warranty - which is a lifetime warranty on apple products and limited warrant on non-apple products (as long as I don't physically damage it myself)
2) Credit Card - there are a few other reputable shops in town that are reviewed well, but were cash only. This place takes credit cards for a small flat fee.
Good service, good quality work, fast solution and all in a legit shop that I can feel secure that they would handle the warranty needs that my company requires.
SO - If you break your screen while out here on a wild time for a convention or whatever else - a quick 15 min drive off the strip will get you right again for less than a few drinks and hands of blackjack.
