Once again keeping to the every-2-weeks cycle, Apple has released iOS 4.1 beta 2 for developers. If you've got an account, head on over to developer.apple.com and update your SDK and firmware.
We're guessing Apple plans on doing what they've done in year's past -- keep releasing betas until they hold a fall Special Music Event and show off the final version along with a new iPod touch G4.
If anyone notices anything new in beta 2, we'll update!
