Multiple Rumors Hint at U2's Possible Involvement in iPhone 6 Launch [Updated x2]
Most of the rumors seem to come from a recent video shoot U2 did in Dublin, which was conducted in secrecy with "black sheets strategically placed to obscure what was happening from public view." Music promoter Stephen Browne managed to snap a blurry photo of the shoot, and he says the "focus of the 'video' on the bridge last week was a phone." It is impossible to tell what device is depicted in the photo, however, or if the shoot revolved around the iPhone.
According to CNET's Shara Tibken, it's also possible that Bono might be a "special musical guest" at Apple's upcoming iPhone 6 event on September 9. The event will be held at the Flint Center at De Anza College in Cupertino, and Apple is in the midst of constructing a massive structure on site.

Apple and U2 have had a long partnership, as Steve Jobs and Bono were good friends. Starting in 2004, Apple released several special edition U2 iPods, which included the band's signatures and U2's music. Apple has also been a longtime partner of (Product) RED, a charity founded by Bono.
It is unknown if these whispers and hints of a U2 iPhone 6 tie-in and possible performance are accurate, but it appears to be a possibility given all of the circumstantial evidence. Apple has plans to debut its iPhone 6 on September 9, which is, coincidentally, the same day that the first single for U2's newest album is rumored to debut.
