Google just released a Java-based Gmail client for your mobile phone.
Compared to accessing your Gmail via POP, the new client:
- keeps read and starred status in sync between your phone and the web-based UI
- features infinite scrolling (you'll find no "click here for next 10 conversations" link)
- groups emails in conversations just like the web UI
- enables viewing attachments
- and much more.
Compared to accessing the web-based version of Gmail from your phone, the rich client feels a lot snappier because it preloads emails in the background, and it looks a lot prettier (no offense to the mobile web-based version--you can only do so much with a mobile web browser).
I can't begin to tell you what a joy it is to scroll through my Gmail using the scroll wheel on my Blackberry Pearl.
