I changed the hosting of my repo from Github to Bitbucket. I like Bitbucket because not only does it house the code and history, but also it ties in with a bug tracker that allows for tracking (and assigning) of bugs, but also collaboration with developers.
To remap my remote repo, I did this:
git remote set-url [example] [git://github.com/user/test.git]
[example] = repo name
[git://github.com/user/test.git] = new repo url
