Apple has been busy updating their Dev Center with another iOS 5 beta update, and today developers can go and grab iOS 5.1 beta 2. If you are already running iOS 5.1 beta, you can just do an OTA update and be done with it. If not, you'll need to download the update and connect to iTunes to install the beta. You can now grab iOS 5.1 beta 9B5127c for iPad, iPhone, and iPod touch, alongside Xcode 4.3 Developer Preview 7 for Lion (4E57a)
