Come on...
It's so annoying to read all of these "pay 99 dollars", "it's not possible unless you're a dev", "it's beta software, unless you're a software engineer, stay away". Every beta, since the iPad came out, has been able to be "option+ update"-ed onto a device. I've done it with EVERY beta, developer preview, whatever you want to call it, since iOS4 was first being tested. I tried putting iOS5 on my 1G iPad last night but couldn't get past the 3002 error. I even tried to restore my iPad with iOS5 but still couldn't get registered. I DFU'd back to iOS4 with no problems. So perhaps this beta truly can't be put onto a device that isn't registered (I'll keep looking for a solution), but for people to say that it's never a good idea to try is idiotic. It's like they're hoping Steve Jobs personally reads their post and awards them an Apple branded medal of valor. I'm not a developer, but I am a power user who wants to try the newest software (it makes no sense to join the developer program, don't try to justify it) and I don't think I'm alone.
