There are often some local outfits where you can actually see the work being done and get a discount over the web prices. At least I saw a couple in Chicago that were rated halfway decent for less than the quotes I got from ATT. It depends on where you live though. Cities are generally better since there's often more phones/competition. Since the One X is new, it will likely cost you a little more unfortunately.
Don't forget to factor in the total cost of the phone to the carrier, not what you paid, e.g. the subsidized price. That's why the screens/digitizers are going to cost so much vs your out the door price for the phone with a contract.
Also check howardforums.com for recommendations on where you might send it for a better price.
Can anyone recommend a good, trustworthy website where I can send my son's HTC One X for a full screen replacement? (the phone still works properly but the screen is completely cracked). I have already contacted both HTC and our carrier (AT&T) regarding this matter but HTC's quote was astronomical ($220) and AT&T could not assist us. This is a brand new phone which we just received as an upgrade so the phone itself only cost $49 (and sadly, yes, I failed to get insurance on the phone prior to purchasing it). I don't mind paying a reasonable price to replace the screen but I certainly don't want to get ripped off or, worse yet, pay for some unscrupulous website to either not fix it properly and/or never get the phone back. Prior to coming here (which I really should have done in the first place) I did some online research and found two websites so far: cleanplanetrepair.com and doctorquickfix.com. The BBB rated the first website better than the second one but neither is affiliated with them....and searching for some type of customer reviews about both sites came up short as well, so I am desperate for any advice/assistance anyone can give me. Thanks so much.
