Did you know that BlackBerry can now be used just like an external modem for a laptop computer, so that a laptop can have full Internet access? This is useful when you need to do certain things that a BlackBerry cannot yet do. Increasing numbers of success reports have caused me to post this message. (Note: Mark Rejhon has not himself yet successfully used a BlackBerry as a modem; I am aggregating information). Sometimes, it is still tricky to set up a BlackBerry as a modem for a laptop, but this feature is becoming more and more common in cellphones, and BlackBerry models are following suit.
