Apple has revised its iPhone Developer Program License Agreement changing the terms and conditions to insist iPhone applications are written in native code.
An "intermediary translation or compatibility layer or tool" is now prohibited, which means iPhone developers will no longer be able to use Adobe's iPhone compiler software to help build applications.
Section 3.3.1 of the iPhone Developer Program License Agreement now reads as follows:
Apple, and particularly CEO Steve Jobs, has not been a fan of Adobe in recent months calling Flash "buggy," and claiming the company was "lazy".
In response, an Adobe spokeswoman said: "We are aware of the new SDK language and are looking into it. We continue to develop our Packager for iPhone OS technology, which we plan to debut in Flash CS5."
Adobe will launch Creative Suite 5 on 12 April, including new versions of flagship software titles Photoshop, Illustrator and InDesign.
Adobe is offering the creative community the chance to register for an online launch event that will take place on Adobe TV next Monday, 12 April at 4pm.
