title: Is there a way to downgrade from iOS 5.1 to iOS 5.0?
body: <p>I accidentally upgraded my iPhone 4 on 5.1 and now I can't test on Xcode 4.2 on my snow leopard. I don't want to upgrade to lion to download xcode 4.3 because I heart many people that said it slowed down their macs and had other several problems. Is there a way to downgrade from iOS 5.1 to iOS 5.0 and be able to test again my applications on xcode 4.2 on my snow leopard? I'd be grateful if someone helps thanks. </p>
