问题 From my extensive reading, the iOS 5.1 localStorage/WebSQL behavior change that Apple instituted has been fully rolled into Cordova 1.6.0. However, while running on my (new) application on Cordova 1.7.0 and iOS 5.1.1, I am still seeing ugly, incorrect behavior. I use window.localStorage to store and retrieve data.
