I updated to the iOS 4.2 Beta last night. So far it is running very well and looking great. The multitasking bar is my new best friend of course, and folders are a god-send. I haven’t tried printing out yet because it requires you to run a pre-release version of Mac OS X, which I’m just not wiling to do right now.
I’ll share more on 4.2 very soon.
Anyone else trying it out yet? Liking it?

Get me on the list…Help a brother out.
How does one get the 4.2 beta?
You need to be either a registered developer yourself or registered with a developer as a beta tester or similar. Wish I could help you out, but I'm not a developer, just a registered tester.
