haha dude just do some reading... it's not that tough... took me a few hours to get the knowledge to do it....really less than that.

 

Someone not comfortable doing it themselves shouldn't have a phone with 2.2, since the custom hacked ROMs find and resolve bugs almost daily so at some point in the near future you'll be wanting/needing it done again... and again... etc.

 

just follow the process on the youtube video series by mobiletechvideos. You can't go wrong, the video is specifically for the samsung captivate. The only way you can mess up is by letting the battery or cord fall out during the process. And the other problem some people have is when they restore system apps with titanium backup so you should only backup user apps, your contacts, and bookmarks. Also, if you're a beginner, i would recommend flashing a very basic stable rom like cognition 3.04 or maybe serendipity 5.x
