Apple to Provide Adapter for Smaller iPhone Dock Connector

iMore, which was first to report on the smaller dock connector back in February, has now confirmed with its sources that Apple will indeed be offering an adapter to provide backwards compatibility with accessories designed for the 30-pin connector.
While this seems like it should have been filed in the obvious drawer, because of all the questions we've been getting, and posts we've been seeing, iMore reached out to the original sources that gave us the new Dock connector story way back in February just to make doubly sure -- and yes, there will be an adapter for the iPhone 5's smaller Dock connector that will let it work with many of the accessories designed for the old 30-pin Dock connector.The report notes that some accessories may not be compatible with the adapter given their fit, but many accessories will continue to work using the forthcoming adapter.
We haven't heard if one will be included in the box along with the iPhone 5, or will only be sold separately, but either way, come October, you'll be able to get a new-to-old Dock adapter from Apple.
While Apple is generally not afraid to abandon legacy standards in order to make changes advancing new standards or designs, the company has sometimes offered adapters to help ease the transitions. Perhaps the latest example is Apple's new MagSafe 2 power connector found on the new MacBook Air and Retina MacBook Pro. Apple offers a separate adapter priced at $9.99 to allow users to use older MagSafe power supplies with the new machines. The company is also including a free adapter with the Apple Thunderbolt Display, which still uses the original MagSafe connector for providing power to portable machines.
