Hi, I am grandfathered into the ATT unlimited plan and want to eventually upgrade to iPad 2/3 from iPad 3G. I heard ATT is allowing users with unlimited to upgrade to iPad 2. How is this process handled and are there any problems? Do they just reprogram the SIM card? I spent three hours activating the unlimited with ATT at the undisclosed 800 number after I ordered the unlimited on June 6, 2010 and received it on June 23, 2010. Not fun. I'd also like to give the old iPad to my wife. How does she get service activated on the old iPad? Thanks.
