+1 for moving to 5.0 minimum. We're planning to drop 4.3 support from the next major release of the Wikipedia app as 4.x is just so buggy, and now anybody who can download our app store releases can also be running iOS 5 or 6 (3Gs and above). We've only got one 4.3 test device left and I'm just itching to update it...
