Apple is now seeding the iPhone OS 3.0 7A341 GM (Gold Master) to developers but warns it will lock your iPhone into “testing” mode.
This version of iPhone OS 3.0 should only be deployed on devices dedicated for iPhone OS 3.0 GM Seed software development. By installing iPhone OS 3.0 GM Seed software on your Authorized Test Devices, these Devices are permanently “locked” into testing mode and cannot be restored to an earlier release of iPhone OS. Bear this in mind before installing the software.
We haven’t given this release a shot so we strongly suggest that normal users DO NOT install the iPhone OS 3.0 7A341 GM seed which will be available everywhere soon, thanks to torrent.
