I am new in mobile software development. I would like to know two simple solutions.

1. Is it possible to transfer data between two nokia mobiles.If possible then how can I do this. In my place the two mobiles are connected with two pc. I can talk through the two mobiles.

2. Can it possible to get intternet connnection through the mobiles. I heard that there is AT commands. But didn't go though that.I am using my landphone to connect to an internet service provider.
