Apple has released an iOS update for iPad, iPhone, and iPod touch. We recommend that you upgrade to this latest iOS update ASAP, as Apple has fixed a number of bugs that lead to iOS-wide app crashes (including crashes in Apple’s own native apps). The main feature touted in 4.3.2 was improving connectivity to Verizon 3G networks, but we’re finding it fixes a lot of other little gremlins that 4.3.1 introduced.
When you get a sec, tether your device to your PC and get the latest. Random app crash instances will go way down.
