Today I was standing within WiFi range of an at&t store, took my phone to check something and by doing doing so woke it up. It proceeds to connect automatically with a prompt or a warning to the at&t store's wifi. I have since reproduced this: iOS 5 will automatically connect to any router broadcasting an attwifi SSID. WTF? Man in the middle, packets-sniffing etc. Come-on Apple! I filed a bug report. Googled it. This problem is known but I had never heard of it until I experienced it today and then researched it. Does iOS 5 send email accounts passwords in the clear?
