I live in NYC which means I use the subway system a LOT. Obviously there is no cell service when on the trains. However with the original iPhone you couldn't sent an SMS message when you had no service and then have it automatically send when you are back in a coverage area. This was my #1 complaint about the original iPhone. Withe every other cell phone you can do this and it was frustrating that I couldn't do work when on the subway. Does anyone know if this was fixed on the 3G version? Thanks.
