Speaking of iPhone OS 3.0, Apple have released the latest pre-release version – beta 4 – to developers.  The preview is joined by a pre-release of iTunes 8.2, which is required to activate iPhone OS 3.0 beta 4 on an iPhone or iPod touch. 

According to developers taking part in the iPhone OS 3.0 beta program, key changes include the requirement for 10.5.7 or later in order to synchronize the new Notes app, while the Store page now has information about the user’s iTunes account.  This is linked to Apple’s servers, taking users to a webpage where they can tweak their credit card settings from the iPhone itself.

As for iTunes 8.2, the app now allows users to play music on their computer while updating their iPhone or iPod touch with new software.  More interestingly, it also warns that it will check a connected device to see whether it’s registered to the developer program prior to installing the latest OS 3.0 beta.
