Microsoft confirmed earlier reports that the company's SkyDrive iOS app update has been delayed by Apple, but it appears the issues are bigger than just SkyDrive. All Things D reports that Apple and Microsoft are locked in a battle over a 30 percent cut of Office 365 subscriptions for Office Mobile. The Verge exclusively revealed details on Office Mobile for iOS, including plans for a subscription version to edit documents on the iPhone and iPad.

Microsoft has been reportedly pushing Apple to adjust its developer license agreement that splits the cost of subscription services between a developer and Apple 70 / 30 percent. All Things D says Apple is sticking to its rules instead of negotiating a special deal for Microsoft. The additional disagreements explain why Microsoft's latest SkyDrive iOS app has been put on hold. A company spokesperson confirmed to The Verge earlier today that it is "in contact with Apple regarding the matter and hope to come to a resolution," for the SkyDrive app.
