Anyone else on iOS 5.1 having issues where reconnecting to WiFi from sleep doesn't happen? Hey all updated to 5.1 from 5.0.1 and everytime my iphone goes to sleep it won't reconnect. i have to manually type in the password and it won't "store" the password if you like. I also don't get the option to FORGET THIS NETWORK like in previous builds. Can someone help? is it a bug?
