Those fractional parts (thanks Paul for a more extensive list)
are very much unofficial. So disagreements about detail are
possible.

Your 2.5G icon may mean that you have a GPRS session going, and
not just that GPRS is available from your serving cell. Unless
you've got GPRS always active, something may have started a
session, and in which case it may eventually close when the
inactivity "linger time" expires.

Thanks.
Been checking....comes on when I turn the phone on. Changes after an
hour or so.
Should I be worried about charges for service?
If so I will have to figure how to turn it off.

Absolutely. It's more of an "understanding" than anything else. I was
fully expecting to get stained by posting those figures, but haven't
yet.

Can't say without knowing what's turning it on. I'd be checking
my bill though.

There may be a configuration setting somewhere in the menus to
start up with a GPRS connection. Or perhaps Optus turns it on
by default to tempt you to use it and spend more. This is
conceivably a setting made via a control SMS you never saw.

Will be checking!
Thanks.

My SE K750i on Virgin (Optus) will start up with the GPRS indicator active.
After some period of time, that indicator goes away, and only returns when
I initiate a GPRS session or when someone sends me an MMS.

It appears to be standard behaviour for their network.

3.6G = HSUPA
3.75G = HSPA+

4G = WiMax

I (and the follow-up poster) were only talking about GSM standards. So
UMTS rev. 8 would be the logical item to put there. If we're talking
other non-GSM standards, the list above would be as long as my arm.
