iTunes Match online content resetting for launch
Apple has told those developers currently subscribing to the beta-era iTunes Match that it will reset the cloud side of their libraries on the morning of September 26 at 12PM Eastern. Early adopters are being asked to turn off the feature on any of the beta iTunes and iOS 5 clients before the reset arrives. It's not evident how long the reset process would take.
Any content stored locally won't be affected by the handover.
Contrary to some early rumors, the finished iOS 5 release didn't reach developers on Friday. The timing of the iTunes Match reset implies that it might come on Monday instead. Rumors persist of an October 4 iPhone 5 unveiling that would give Apple only a limited amount of time to finish the OS, flash new phones with it, and ship it to partners.
