My 32GB iPhone 4 is currently running iOS 4.2.1. Hanging with Friends now refuses to run with anything less than 4.3, and so I want to upgrade to 4.3.3 but no later. Apple (say it holding your tongue, and it's still an understatement) won't let me upgrade to anything less than the latest and far from greatest iOS6, though.
I have an IPSW file for 4.3.3; they're widely available for any iOS version. I found a program called tinyumbrella that gets me over the initial hump in getting iTunes to apply the 4.3.3 IPSW, but I still run into errors later (a 16 hundred-something error). I've been following this guide; it's meant to downgrade your iOS, but I figured it should work to upgrade to <6 too.
Anyone successfully done this before?
