Here’s some good news for you T-Mobile G1 users out there who have fallen in love with the ContactSync app. Wrike will be releasing ContactsCalendarSync, an upgraded version of their best-selling sync app for the Android phone, on March 26.

This new iteration not only provides two-way syncing between your G1 Android phone and a Microsoft Exchange Server 2007, but now also does calendar/appointment syncing as well. It will, however, cost you $24.95 to download once it goes live in the Android Market, but if you’re really in dire need of such an app, it’s probably a reasonable price to pay for the added functionality you’ll be getting on your T-Mobile G1.

Nonetheless, if all you need is a contact sync app, their ContactsSync app is likewsie available, and best of all, it’s still free to download and use.
