Gmail just got an update to add some of those cool UI improvements -- and it's been moved into the Android Market. This means that from now on, you won’t have to wait for system updates to get Google’s latest and greatest e-mail client. You will find some pretty cool improvements in this particular update including a much better implementation of how "quoted text" works within e-mail threads as well as limited (for now) support for Google’s new Priority Inbox feature – just be sure to enable it on your desktop version of Gmail first.
You need Froyo to take advantage, and we've got the download links after the break. [Google]
