    When a phone specifies that it has GPRS, Edge, HSCSD etc does that mean that
    the phone has hardware which is only capable of that speed?

    Depens whose specs you're reading.

    If looking at specs provided by the handset maker then yes, if looking
    at network-supplied specs then they usually quote their own limits.

    Gprs is a contended service, so the more peeps using it though the node the
    slower it'll go. Max would be about 30ish k (if you're really lucky) down
    to a few bytes a second.. HSCSD is the same a an old dial up connection,
    speed would depend on line noise etc...

    Whats the real state of affairs with 3G and EDGE? Can you actually get these
    speeds on all networks if you have a phone that supports it? Do the network
    operators charge through the roof on pay as you go for using a fast speed? I
    was looking at getting a sim free EDGE compatible phone to develop 3rd party
    apps for but if they're going to charge a fortune for an unreliable service.
    I thought 3G ran over the old analogue TV airwaves - if so you should be
    able to receive streaming video across the country?

    I don't think you can get EDGE in the UK (I'm sure someone correct me if I'm
    wrong there). 3G runs on it own network, that what all the operators have
    been upgrading over the last year or so. It's not broadcast in the same way
    a tv is, it's sent straight to the device the same way a call or a sms is.
    So you have the same problems you have with grps, the more users, using the
    service the slower it gets and if your using it for streaming tv you soon
    hit the point where it's not usable at all, as there's not enough data
    arriving at the device to keep even a 15 or 12 fps stream going...

    There's a trail somewhere (Swindon ? Oxford, maybe) where O2 are using
    broadcast style system (I can't remember what system their using, anyone
    know of the top of their head?), but that's small scale and only for a few
    months as they don't have access to the channel for longer than that.
    There are moves to try to use the old analogue bands, but
    A: there don't become free until 2010/12 when analogue gets switched off
    for good and
    B: lots of other areas want to use the same bandwidth for other things.
    It's down to whoever gives the right gov dept the biggest back hander !!
    (Sorry, did I say that out loud..).

    The Orange 3G office card downloads files at about 30k a second, which
    is fairly rapid for a mobile device, about half what you'd get from a
    512k ADSL line or thereabouts.

    OK, just found this on the O2 site about their tv trail...

    Use's DVB-H to brordcast the progs

    GPRS, Edge and HSCSD all can operate at different speeds, depending on
    the capabilities of that implementation.

    So I really can't understand your question. Sorry.

    IME, they really can give the full 384kb/sec download speed if you are
    in a quite traffic area with a good strong signal.

    That's two thirds of the speed of a 512k ADSL line, however, in those
    conditions it /seems/ as fast as ADSL - but the uplink seems much
    slower.

    No where near this when you consider handshaking, error handling , number of
    users, etc Jons comments above are a realistic assessment ie comparable with
    dial up

    Bollocks. I have used it and got that speed. You need to be in
    excellent signal and somewhere there are not many other users, but it
    most certainly is possible. The handshaking does not come out of the
    384k.

    EDGE is available on Orange on certain masts.

    Indeed it is - the hardware has been slowly rolled out over the past year or
    so. EDGE coverage is - very roughly - in line with 3G coverage.
