Wirelessly posted (Mozilla/5.0 (iPhone; CPU iPhone OS 5_0 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9A334 Safari/7534.48.3) I was at the mall when I noticed my new IOS5 iPhone auto-joined the attwifi hotspot. Annoyed - I tried to turn the auto-join off, but I accidentally joined an unknown neighboring wifi instead with SSID - HP43.something. I spatzed out when I did that as I am very conscientious of my wifi security. I don't even like using public wifi hotspots much... I did disconnect from this unknown network and did a Forget This Network, but I'm concerned if I punched a security hole in my iPhone environment somehow? I keep hearing about these man-in-the-middle attacks that are possible with rogue access-points that can steal your iPhone emails and stuff... Should I be concerned about this from my accidental joining of unknown networks?
