Not sure if this is in the correct place but here goes: At work we have a wi-fi for guests that you have to sign in with a password. My iphone is set to remember this wi-fi and when ever I use my phone, the sign in screen from the network pops up. It only remembers me as long as I keep my phone active. Even if the phone goes into standby or sleep or whatever its called for a minute, if I go to check my email or facebook, the wi-fi network asks me to log in again. HOWEVER, my friends' android phones log in automatically. They were asked for this password once and never again. So, anybody know what I'm doing wrong that this wi-fi network keeps asking for the password when other phones just log in with no problems?
