Dominik let us know about a post by a Sprint admin on their official forums about OS 220.127.116.11 for the BlackBerry Tour. Looks like it is quietly being pushed out through Wireless Updates for select individuals. Seems like some people are not having that much luck with the update but it looks like it is coming soon.
Check it out and see if you have it by going to Options>Advanced options>Wireless Update
If it works for you let us know!
