AT&T really needs to add a data setting the the phone to enable/disable edge data. That way people can turn off the data feature and still use their phones as ipods and for emergency phone calls. Would disabling the email auto-update solve this problem? Or are their other automatic functions that automatically engage EDGE without the user knowing?
I'll experiment with that and report back. Not that I don't believe you guys. But I know when my Razor phone was off, or on Airplane Mode. It was still working. The only way to truly shutdown a new generation cellphone is to remove the battery.
Easy to test. Put the phone in Airplane mode and you'll see WiFi and Bluetooth be set to off. Try to set WiFi or Bluetooth mode on again, it will ask you if you want to turn Airplane off because it can't turn either of them on while in Airplane mode.
I never said Airplane mode means that the phone is off. Only that all communications are off.
