Since AT&T usually recognizes all iPhones regardless if it's international or from ATT locked. Wondering if anyone's put a nano sim from ATT to use with Verizon's iPhone 5 with has unlocked GSM slot for fake 4G/3G. I have both ATT and Verizon service. Would be cool if I could use the Verizon iPhone 5 on ATT's $10 family unlimited data plan if ATT's system do not recognize the phone. We all know people use Galaxy Nexus (GSM), T-Mobile's S2 and S3 (which both support Tmobile and ATT 3G bands). We all know most people who use those phones use the $10 family unlimited data plan cause ATT does not recognize those phones.
