And by the way for firmware upgrade you'll need to use the Sony Update thing right?
If so, it's damn buggy. You have to download a 24meg file from the internet. It then autoupdates 2 times(dont ask me why) each takes 10 mins on a 512kbps line and finally you can search for new firmware. I haven't tried this out myself ,I'm on dialup
I'll be doing it soon at my friends place. Thanks.

Take a look at this. There are some bugs with the new version. And is it really necessary? I've no problems with the phone.
