Besides the fact that in order to do this you would need to illegally obtain the beta firmware, this doesn't work anymore. This was only true for early beta versions - tools haven't been updated to activate or jailbreak newer devices, and you still need a provisioning profile if you DID get 2.0 activated without being in the program.
True. I read a bunch of FAQs and saw a video showing how to use PwnageTool 1.1 to atleast jailbreak / activate (but not unlock) some beta build of 2.0. These docs/vids were made around April so I can understand what you're saying about it not working now. However, I thought I read somewhere that the iPhone Dev team knows what to do with the latest builds, they're just purposely not releasing it for fear of Apple closing their exploit. I'm confident that a solution will come out that will atleast let me put my app on my phone without having to ask Apple's permission first.
Thanks!
