I have an I pad2 and now am getting the IPhone 4S, I was considering giving the ipad2 to my wife and purchasing a 3G, having the iPhone on unlimited Internet access can someone help me if it will benefit me to purchase a 3G or should I just stick with the Ipad2
Save the money. Get a tethering plan with your iPhone 4S and use that with your current iPad. Generally you can add a 2 GB tethering plan for around $20 a month. If you get a 3G iPad, you will cost a minimum of $630 and you still will have to get a 3G plan for $15 to $50 a month depending on how much data you want.
