This program allows you to get onto any eircom wifi router with the default WEP password set. it duplicates the functionality of http://s4dd.yore.ma/eircom/ which is of little use if you don't have a net connection. As the 3gs has really bad reception in rural ireland this is really of use for emergency emails an skype phone calls or cases in a pub or restruant where you are a paying customer & they won't give you net access The program was compiled to run os 2.2.1 or greater and is know to run on 3.0 & 3.1
