I don't know if I should answer this without a helmet and bat in hand or not... Are you serious? The network isn't designed to service phones which are hurtling past 5 towers at 250km/h above their intended elevation. In my personal experience the iphone 4 is by far the best phone to use in an aircraft. Out of the several nokia's and "next G" phones I've used the iPhone will always hold reception longer, is very capable of making calls and internet connections up to FL250. No phones work well around populated areas because of lost connections and network congestion between towers.
