A couple of years ago, Blackberry devices were known for their email capabilities. Now it seems the first thing that comes to mind when you mention Blackberry is BBM—Blackberry Messenger—which could be soon finding its way onto iOS and Android devices as slimmed-down versions of the popular messaging application.

Ping! is an iDevice to iDevice messaging application (similar to BlackBerry Messenger on Blackberry smartphones) that makes use of Apple’s Push Notification service, and is said to be a replacement for SMS or other IM clients. Ping! uses data from a 3G/EDGE or WiFi connection rather than SMS messages, and therefore can potentially save users a lot of money.
