Another Android app that has been upgraded is Bump. Bump will now allow two devices to share apps in addition to other info by tapping two phones together. Well, actually, that's a little misleading. Each person wraps his hand around his/her handset and then the hands tap. What can be shared? Just about everything except your carrier's monthly invoice. E-mails, contacts, apps, photos and phone numbers can all be "Bumped" to another Bump wielding phone.When both parties have the Bump app, one of the users opens the app and selects what item is to be shared by tapping hands. Besides being offered in the Android Market, iPhone users can also find Bump in the Apple App Store.
