There are only two options out there for you: 1) Become a developer, or 2) Find a developer who is willing to add your iPad to their list so that you can get 4.2 However, to be honest, if you're not a dev, then don't bother. The Beta is an OS that is released for testing purposes, so chances are it is not 100% functional nor 100% reliable. On top of that, many apps may not work properly in their current version (that's why Apple sends the devs a Beta), so even if it does run smoothly (which I doubt) then chances are quite high that you will encounter several issues with the apps you have. At the end of the day you need to ask if the aggrevation that you most likely will incur due to problematic, reduced and/or unreliable performance is worth having folders (because many apps do not yet support multitasking, so this would be ruled out as a benefit). If you have come to this thread by searching before posting a new thread asking "OMGWTFBBQ I NEEDZ 4.2 NOWZ - PLZ HALPS ME HAKRZ!", then congratulations. If you haven't searched and posted a new thread (which will probably be promptly closed), then you probably didn't read this so I can safely call you a right numpty without hurting your immature feelings.
