NLxAROSAPhillip, the difference between WiFi and 3G versions is not just the 3G. WiFi version also has no GPS. Other than that: identical.
Maybe save some money and jailbreak the iPad 2?
Why would anyone do that? It is kinda dangerous to go into the iPad's root. It is like, one thing you change then BAM! You're iPad is messed up! So I wouldn't recommend it.
