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.
