Is there any way of getting unlimited data on the iPad? Kind of like how to get unlimited data on the iPhone 4? I know I'm going to be going over 2GB (somewhere between 4 and 6) since I plan on using this to replacing my iPhone. I was thinking of maybe adding a new line to my family plan for $10 then putting that sim in my old iPhone 3G to get the unlimited data, then putting that sim in my iPad, so for $40 (before my dad's government discount) I can have unlimited data for less than the price of 4GB. Would this work? Or would AT&T change the data plan once they detect the IMEI of the iPad? I know I'm being super cheap with this, but it just sucks knowing that I'll be going over the data plan. I use about 1GB/week on my iPhone and that's only because the battery dies half way through the day. Thanks.
