Hi all, thanks in advance for any of your input. Does anyone here currently have AT&T cell service and is using an unlocked smartphone without paying a data plan? I just bought my son a Motorola backflip (from ebay) and planned on purchasing an unlock code so that he can use it without paying for the data plan. I figured he'd be able to use WiFifor data and of course we have an unlimited texting plan. 2 years ago, I used to use an unlocked iphone (1st gen.) and would be able to use the wifi and AT&T never had a problem. But now I'm reading that AT&T will be able to automatically detect a smartphone by the IMEI number, and will therefore charge for the data. ...And then without having a "Plan" I will be charged a ton of money. Please reply if you have personal experience with this situation. Thanks!
