I love my Ipad 2. I only use my laptop for homework at this point. I have the White 16gb Wifi version. I also have an Iphone 4s. I was wondering if you think it would be worth it to upgrade, and if so should I get a Wifi only version or the 4g version? Not many places in my area have 4g yet, and I use my Iphone for whatever I need on the go, because it is easier to carry around and just pull out of my pocket obviously. So my question(s) are, do you think that the upgrade is worth it, around how much could I get for my Ipad 2 if I sold it, and is it worth it for me to get the 4g version, since I am usually around a place with Wifi, or I usually have my Iphone on me. Thanks in advance.
