Twidroid, our favorite Android Twitter application, just received an update to 2.5.1 (now 2.5.6) and has introduced a PRO version for Twitter enthusiasts. Twidroid revamped their design in this update, bringing a sleeker design which includes a revamped menu bar. Though the icons are a wee bit small, the change is welcome and we're glad to see Twidroid get better. The Twidroid folks recommend uninstalling the current Twidroid and doing a fresh install of the updated version.

The real news is that Twidroid PRO is now available for Android users and it includes features such as: multiple account support, desktop widget, video posting, color themes, and a 'neat black pro application icon'. Twidroid PRO is available for $4.89 via Android Market--we personally think it's a worthwhile upgrade, but it's up for you guys to decide for yourself.

Who uses Twidroid? Who uses another Twitter application? And who doesn't even use Twitter?
