Ruby Version help

Ok, currently I'm using Go Daddy as a host. They provide Rails version 2.开发者_Go百科3.2 so I'm assuming I can't use rails 3 on their server. I'm willing to remove Rails 3 and install a previous version if need be but i'm not sure which version I need and whether I could get a windows self installer as with rails 3?

I would suggest using ruby version 1.8.7 available here: http://rubyforge.org/frs/download.php/73719/rubyinstaller-1.8.7-p330.exe
