This is an old thread, so you're probably not still looking, but if for some reason you still need proxies, check out:
SilverSurf Proxy Unblocker - Unblock MySpace and More!
911Surf MySpace Unblocker - Surf From School!
Go-Fish MySpace Proxy - Unblock From School & Work!
Proxaroo Bypass Filter: Surf Anonymously at Work!
Good luck!
Edit: Wow, that's pretty cool how the forum pulls the title tags from each site... Nice.
