Google, not ones to lag behind, announced the second version of their mobile Gmail application for BlackBerry phones and J2ME-supported phones.

Google described their efforts as follows: “We rearchitected the entire client to push all the processing to the background, greatly improve the client-side caching scheme and optimize every bottleneck piece of code we came across.”

Additional features include the ability to have more than one email in draft form, the ability to manage more than one email account at a time, the addition of shortcut keys, offline support and more. If you want the update, point your mobile browser to m.google.com/mail to download the update.
