With some Official OS’s Releases a few days back and rumors/news about OS 5.0.0.536 floating around the interweb it was just a matter of time to see this one coming out.

Remember: this is beta software and if anything goes wrong or make your phone act crazy your carrier will not give you support. Delete the vendr.xml file. Do not install if you don’t feel comfortable doing so.
