I just love it when people say 'the type of bdtawidnh", as if a kilobyte from an iphone differs from a kilobyte from any other smart phone.Yes, in 2005 no carrier's infrastructure was built to handle that type of stress on their network. Today, in an industry where smart phones are prevalent and basically a standard, every major network can handle an iPhone. This especially holds true for a corporation like Verizon, which has an array of smart phone products that, according to studies, far exceed the data demands than any other.AT&T decided to play Russian Roulette by not allocating enough of its massive revenue gains towards expanding and strengthening their network early on, and now they are paying the price. Every other carrier has the benefit of learning from AT&T's mistakes.That means: if you have AT&T and you plan to stay, the only major benefit you will see is less calls dropped that shouldn't have been dropped in the first place. As far as the 'no data while making a call line'; (assuming speculation is true) the 2011 released iPhone will likely be on Verizon's LTE network, which will not have the disadvantages of its predecessors.
