It's here, the moment BlackBerry owners been waiting for since the original iPhone launched: iMessage. Apple has just announced its new data-based push messaging service at WWDC, which looks to be a full-on competitor to the venerable BBM. This service works on an iOS device of any flavor, and lets you send text messages, photos, videos, and contacts to anyone else with one too. It also supports group chats and integrates with the new Notification Center in iOS 5. According to Scott Forstall, it "works over WiFi or 3G, in case you were wondering," which is yet another blow for RIM. The final nail in the coffin for those of you who simply 'can't live without BBM:' delivery and read confirmations. Boom.
