How Do I Update to iOS 4.3 beta 3

[MGH]

I part of the Developers program in Apple. And I already downloaded ios 4.3 beta 3 but how do I update my iPad to it?

(I right now have ios 4.3 beta 2 and want to update to beta 3).

I completely forgot what to do.
It's right now in Recovery Mode and the only option I have is to Restore it - but it'll go back to iOS 4.2.

Please help!

Thanks In Advance.

download the 4.3b3, go to itunes, hit SHIFT + Restore, select the 4.3b3 ipsw and restore. or you could just restore to 4.2.1 and then update.
