Do you think it is possible that the "Side Convenience Button" is available to be programmed for future PTT (Push to Talk) support on the Sprint/Nextel network?

Also, on Sprint's website it mentions that with the implementation of their new EV-DO rev A network, that high performance push to talk will be enabled!

Does this mean that Nextel PTT will be obsolete?

Please share your thoughts.
