That's right folks, the Windows Live Messenger beta is now officially public. According to a press release issued by Microsoft this evening, the latest build is now available for download at ideas.live.com. The statement also details the widespread availability of PC to Phone calling with Windows Live Call, provided by Verizon Wireless. Also, now available for purchase are the Windows Live Messenger cordless phones, produced by Uniden Corp. and Phillips. Chris and myself got a few minutes to see one of those this week in Redmond, but more on that later. If you have been dying to try out Live Messenger, but somehow haven't been able to sign up yet, everything is out in the open. Go grab it.
