Google recently launched a mobile java client for Gmail. You can download it by pointing your mobile browser to: gmail.com/app
When I first tried it I got the error “This program requires a working data connection … Please check your signal strength”. Strange thing is I do have a working data connection that works with regular browser access and java apps like Opera, so what’s wrong with Gmail….
Turns out it’s only compatible with Gmail accounts that are set to US English – mine was on UK English. Logging into my account from a desktop browser and changing my preference to US English fixed it – fast Gmail on my phone… sweet!
