I am developing one GPS based application. in that i given few default values to user those are phone number which will used to make a phone call. and server address which is used to sent the location data to server.. In this I got 2 major and critical problems..
1) I have hide that default values in regular menu and that should display when user presses some key or combination of keys then only it should display.
2)When ever the Default phone number and server address is changed at provider side that should be updated at user side that should happen through SMS from a specific number in a encrypted format by accepting that SMS those values has to change
Please Any body knows about these things help which are very very very useful to me
