I'm looking to buy a Lumia 920 or 928, -off-contract. Buying off-contract I'd be willing to pay full price, new would be great as I'd be assured new condition. But to save a few bucks I'm considering looking into buying used, here on this forum, or Craigslist or eBay. Would prefer someone local who I can meet somewhere (in public, bank or ATT store) and check out the phone in person. Any tips on what to look for, what to ask, etc. My biggest concern would be the phone being bricked, features being blocked or completely locked by the carrier somehow, either due to unpaid balance on previous customers account, or being reported stolen or whatever. If buying a used phone should I just call the carrier from the phone to verify it's legit? Any settings I can check on the phone? Anything else I haven't thought of that I need to look for? Any help would be greatly appreciated.
