I'm writing to you because I would like to have some advice.

My goal is to develop a client/server application using Bluetooth. The server would be a computer and the client would be a cell phone. Using Bluetooth, I want the server to communicate with the cell phone and to ask to the user some text information, like his "Name". So, from the cell phone side, I would like that a window appears asking this kind of information.

The best would be to have nothing to program on the cell phone side. Moreover, I would like this application to work on the maximum number of cell phones.

Which technology would you suggest me to use in order to realize this kind of application?

Thank you in advance for your help,

Best Regards.
