Need someone to develop a java app that will live on mobile phone sms card. This app when triggered, by calling *11 on a mobile phone, will save the address book of the phone to the sim card, give the user a unique pin number, and transfer this file through sms and/or wireless to a remote server.
If a user calls *12 on a phone this will trigger the app to contact the server, ask for a pin number, download the address book associated with that unique pin number, and save it to the phone.
Someone else on my team will handle the IT, network, and db issues.
