I have concerns about what info i am forfeiting when i connect to an wifi network. 1- Am i giving my device address ? Is this unique and resolvable / traceable back to my device ? 2- Am i giving access to any data stored on the touch, whether it be picture,video,music, or even cookies and saved passwords ? 3- Am i open to some sort of dos attack at all ? or is it possible for the touch to be packeted or whatever ? 4- Alot of open unsecured networks seem to be "default" or other generic setups.....could someone explain the logic behind how this occurs and what the pattern is ? Sorry if some of you are cringing reading this.
