Im currently trying out a Vodem and have noticed some interesting behaviour.  Once it's connected, it seems to default to a 3G connection, and will only make a HSDPA connection when I'm using the Internet.  So it keeps dropping back to 3G, which is really annoying 'cos everytime I do something, there's this delay of a second or so while it re-establishes HSDPA.

Is this normal?  The signal strength is 2-3 bars, which is also strange as my Nokia connects to 3G at full strength.
