I just bought a Samsung Captivate from eBay. It currently has 2.1 on it. I read that it can be upgraded to 2.2. However, I don't see any one way to do it. Everything seems very unofficial. (on par with jailbreaking an iPhone) That being said, I was wondering if there's some definitive way to upgrade that I'm not finding though a Google search. Much help is appreciated. Thanks. BTW, I'm running Mac OSX snow leopard if that is any relevance.
