I know that there is already Viigo and Newsgator Go for BlackBerry but this is a new twist on getting RSS to your Berry. IM Feeds lets you setup a feed service that Instant Messages you feed items as they come in. This is a great way to keep up with time sensitive news (such as BerryReview) like the elections. Its also a great way to track packages.
You can get more information by heading over to www.imfeeds.com. The service currently supports AIM, MSN, Yahoo, & Google Talk. Thanks Josep for sending this one in.
Let us know if you use it!
