Hello friends, I have just pre-order the iPad with 4G LTE and done it from Canada, but suddenly due to some work need to move US for couple of months, so it will be a long time over here. Well the new iPad is been supportable with any of the 4G Company over there, but it will be totally different in the US. So the main question of mine is that if I purchased from Canada will it be working in US or not? And also it is possible to use 4G at all? This is very much important for me, as I will be using it for my work. If it will not working then will be cancel the pre-order. Please help me, thank you.
