Hi, I need to develop an application which must convert SMS to Email. The core of the application is, User will send an SMS from their mobile to a particular mobile number (or it can be sent to a server). From there the SMS should be converted to Email and it has to be sent to a particular mail address. I don't know how to proceed; Also I don't know what are the software/hardware requirements. Can anyone assist me in this regard. I am using windows 2003 Advanced server from the PC part. As of GSM modem, can we connect a GPRS enabled mobile phone for it. Also please tell me whether it is possible to develop our own application using windows mobile rather than going for a third party tool for sending/receiving SMS. If this application is possible, kindly suggest me a reference from where we can start with?

You can surely use a Windows Mobile Phone as your SMS receiving device. I'd write two applications - one the smart phone, the other on the server. The app on the Windows Mobile 5.0 Phone receives the SMS messages (using the Message Interceptor class) and sends them to the server. As a communication channel between the smart phone and the server I would use WLAN (instead of GPRS).The server could implement a web service the mobile phone calls to deliver the SMS messages. The server then sends the appropriate e-mail. There are a lot of references and samples available how to implement and use web services - please try searching. The same applies for the Message Interceptor class.
