You are probably aware that iOS 4 is causing several issues on the previous versions of the iPhone; however no doubt Apple is working to solve those issues with a release of a new iOS, which leads to the new that Apple has now released iOS 4.1 Beta 2 to iPhone developers.
According to an article over on TiPb by Rene Ritchie, their guess is that Apple will do what they have done in the past and keep pushing out iOS betas until such time as they hold a Special Music Event where their will show off the final version of iOS 4.1 along with a new iPod Tocuh 4G.
So if you happen to have an account you can nip on over to developer.apple.com and grab the updated SDK along with the firmware.
