Although not functional yet, landing pages for BlackBerry Messenger, BBM for iPhone and Android devices have been spotted by a member at CrackBerry forums. This follows the leaks of user manuals for BBM that were leaked for the iPhone and Android. What this means is that the launch for the most awesome mobile chatting client is almost here. BlackBerry hasn’t given a firm date yet but has said that it will be available this summer. Thankfully, they didn’t mean the Dubai summer.
