Fring for Windows Mobile already has twitter support. But, now it allows you check out the profiles of other twitters and also see who all are following you.
There are two ways to get your hands on the new Twitter 2.0 Add-on… If you have a Windows Mobile, just go to the Add-ons tab inside fring, unsubscribe from the old Twitter & re-subscribe to the new Add-on. And if you’re a Symbian handset owner, simply download the new fring version 3.37 first, unsubscribe from the old Twitter & re-subscribe to the new Add-on.
