TUAW reports that developers seeking to submit applications featuring in app purchase to the iOS App Store have had their submissions stalled by an error message on Apple's end linked to a test account required for evaluating the in app purchase functionality. The reason for the account error is unknown, as Apple has been silent on the issue. Speculation has naturally touched on the Lodsys patent lawsuit threats over in app purchase and upgrade link functionalities, although reports that the IAP test account has been offline for a week now would indicate that the change predates the Lodsys notice letters that were first received last Friday. Consequently, Apple would have had to have advance notice of the letters if the two events are in fact related. Article Link: Approvals for Apps Equipped With In App Purchase On Hold?
