I currently have a 64GB iPad 3G/Wifi if I buy a 64GB or 32GB 3G/Wifi iPad2 can I just swap out my sim card from my current iPad to the iPad2? The reason I ask is because the company I work for is paying for my 3G per month and I'd rather just be able to swap the card out of the old and into the new without any hiccups. Thanks in advance.
