Okay so I have a 3G+wifi iPad 2 ...since iPad's already come unlocked i plan on getting the tmobile 1.5gb data only plan for $25 a month. I need to know if this enough. I'm always connect to the wifi when I'm at home but this summer I'm going to be on the road a lot and I'm basically going to be tethering my iPhone 4 Internet to my iPad so I just basically need this plan for emergencies like if my iPad is lost or stolen I can track it because that's what happened to my last iPad but I couldn't track it through Find my iPhone because it wasn't connected to the Internet. So basically when I'm out away from home I'm tethering my Internet from my iphone to my iPad so will this work? And since I don't have to unlock& jailbreak my iPad for tmobile will it be on edge 3G or 4g or watever? Thanks in advanced!
