We’ve posted about the tour twice now, once in a leak that Mark Hoppus posted, the second in a follow-up article on Rolling Stone… now, Billboard has posted the official tour dates for Blink-182′s first headlining tour in years.

The tour is scheduled to start in Las Vegas and will run all over the country until ending October 3rd in Atlantic City. Tickets are $20-$60 and go on sale May 30th at Livenation.com. The tour is sponsored by T-Mobile, State Farm Insurance and MySpace. Fall Out Boy and Weezer were both announced as openers (although not at all dates)… and Billboard confirmed several more bands that would be joining Blink-182 on stage at various venues: Panic at the Disco, All-American Rejects, Taking Back Sunday, Asher Roth and Chester French.

It’s kind of hard to envision a band that had such a bitter split in 2005 wanting to get back together, and honestly I think that Weezer and Fall Out Boy are much bigger touring forces than Blink, but I guess we will see how tickets sell.
