If anyone uses gMail as their main email account and needs to access it on the go their new J2EE mobile client works very well.

I am on Vodafone pre-pay with a Nokia phone and it works extremely well although I did have to make a setting change to allow the application to access outside Vodafones WAP space etc. Don't ask me what I changed as I can't work it out now.
Anyway, being able to access your gMail in a very gMail style application rather than using the horrible WAPsite for gMail when you're laying on some NZ beach can be very useful!
