iPhone 5 splits into two models, one for US GSM+LTE, another for CDMA+LTE and everybody else

During today's iPhone 5 press event, they made a point of paying special attention to the new radio chip at use in the new smartphone.

"Checking for water damage is pretty simple and something everyone should do before forking over your hard earned cash for a second-hand iPhone 4."

If you're trying to save some money and are in the market to purchase a used iPhone 4 from either Craigslist, eBay, or some other local or online seller, one of the first things you'll want to do is check for any signs of water damage. I see several people in my office each week that purchased used iPhones that mysteriously quit working after a few days.
