    Bluetooth is faster than IR, however you have to remember that any given
    connection is only as fast as the slowest link. In your case, using your
    Nokia as a modem, the slowest connection is by FAR the connection between
    your phone and the internet. Both IR and Bluetooth are faster than this
    connection, so if you use Bluetooth you will not notice any speed increase
    when using your phone as a modem.

    If, however, you were to backup your phone onto your computer, then you
    would notice Bluetooth saving your phone data several times faster than if
    it was done over IR.

    Thanks. I realize the phone <-> internet connection is slow, I just
    wasn't sure if the speed of an IR connection was the slower of the two.
    I'll probably pass on the Bluetooth adapter then; I don't use the phone
    as a modem very often.

    IR is 14.4kbps max.
    BT they say can go to 1Mbps.
    BUT

    IMHO the cellphone is the limiting factor.
    The 3650 has it all. www.nokiausa.com/phones/3650

    If you use GPRS, that is around 38kbps.
    If you use GSM, that is 14.4kbps.
    If you use HSCSD, then it can go 144kbps.

    I use IR to read Email with my 8290 Irda phone+laptop.
    It is convenient.

    Actually CSD (GSM) is 9.6kbps, HCSCSD is 14.4kbps, and GPRS is average of
    48kbps, although in theory it could be almost double than this, but
    operators limit it.

    It could be, depending on what you set the IR speed to. If, for
    example, you are using the default IR speed of 115k, then IR is still
    fa ter than your data connection. When I upgraded to my 3650, I
    accidently left my IR connection speed at 14.4k (the speed I'd set for
    my old 8290) and my slow IR speed was actually limiting my GPRS
    connection!
