I'm not too sure what you mean by 'support' ? Very few manufacturers honor the warranties when products are bought overseas. I always get my mobiles overseas though. Sooo much cheaper and you get it when its actually released. Not left overs!! I will never get a contract or buy a phone locally! (U have to find the level at which the risk vs. price reward is acceptable to you). I recently purchased a 9780 for R3000 at Jumbo Electronics in the Dubai Mall. They even through in a Seagate 1TB USB powered hard drive for an extra R400. Also got an HTC Desire from www_clove_co_uk almost a year ago. It's still awesome!
According to Phonearena.com it is Q3 2011. We'll probably get it a year from now. It was so funny. In the May issue of Popular Mechanics they ran an ad on the "new" Bold (9780). At the same time Blackberry was officially announcing the new Bold 9900 / 9930. I guess its all relative.
