Finally, Apple’s FaceTime is available on Mac computers in addition to the iPhone 4 and the most recent iPod touch. And if you’re anything like me, you have more than just one of the aforementioned devices, but just one Apple ID. No worries, if your Apple ID is linked to a Gmail account, there’s an easy way to effectively use it with every device you have. This is more of a feature of Gmail than it is of FaceTime, but the two combine extremely well. Gmail supports modifications to your standard email address by adding a plus sign and a string of characters between your username and @.

If you watched the last episode of Diggnation, you will have noticed that Kevin Rose released an exclusive rumor about a second-generation iPhone. During the episode, he mentioned that third-party developers are restricted to only applications that run in the foreground, not in the background – there is also no dedicated IM client for the iPhone at this point in time. This is because Apple will be releasing a new iPhone in a few months, with 3G connectivity and two cameras; this will enable mobile iChat video at decent quality thanks to 3G.
