Rent.com has launched a BlackBerry app that allows users to hunt for the perfect apartment while on the go. The free app lets you search for apartments, call or e-mail property owners and manage your favorite listings. The app automatically syncs with each user’s Rent.com account and apartment-hunters can attach their own photos and notes to listings to help them remember the details of a property after they visit. Plus, once you find an apartment, you can report your lease through the app in order to claim your $100 Visa debit rewards card. Check out the app in App World.
