Hey, Am excited to be getting and ipad 2 with 3g data... A few questions for those in the know... -What is the word regarding data/phone hacks? bypassing the att data charge and/or getting the ipad to work as a phone? -how do the voip apps work on the data plan? currently i find them to be cumbersome, laggy, and inconsistent using my iphone 3gs on an unlimited data plan in long island ny. -how well do the data/phone hacks (using my iphone sim in the ipad for example) work compared to just using the miwi app on my iphone? perhaps the question here is, how much is battery life affected on the iphone by using it primarily to tether to the ipad? thanks for your great veteran advice! from an excited ipad newb... r.
