While this is great news for Verizon customers who want the iPhone, there is nothing special about this iPhone 4 compared to the AT&T one released last year. However, there may be a mobile hotspot feature that AT&T has not provided, but we will have to wait to find out more about this option and what the fees will be for it. There is no LTE inside so no support for simultaneous voice and data. As has been pointed out numerous times here on ZDNet there are plenty of reasons to think twice about this iPhone as the market has changed significantly since 2007 when the original iPhone launched. Sascha Segan put together a great post on why the iPhone 4 on Verizon is no mobile Messiah that I recommend you check out.
There is no information on monthly minimum pricing, but you will be required to have a Nationwide voice plan and a data plan to buy the iPhone 4.
