Dear people,

what are all the network parts to send and to receive a message to/from my cell phone? I?m trying to develop a MMS gateway and I don?t know where is the rigth point to start. If possible, somebody gives me a direction.

I downloaded the Nokia Java MMS library, but when I try to run the "" sample, and listen in the port 7000, it returns me the following message:

"HTTP/1.1 400 Message Validation Failed"

What it means?

Thank you in advance,

Marcelo Muzilli
