An unofficial Three UK blog has rumored that the BlackBerry Bold 9900 will be available for purchase on September 15th. This is the first solid date we've seen for the device thus far, though keep in mind it was posted on a Three UK rumor blog and not via an official press release or site. Noted is that the device will be available in black at launch with an all white version to follow a month down the road. We've seen the device listed on the Three UK coming soon page more than once now, so it's good to finally have a date to put in the books. Hopefully other carriers will kick into gear now and drop some release dates of their own. Bring on the Bold 9900!!
