MIDP 2.0 and socket

[Gianluca]

Hi,

I have a Motorola V525 with MIDP 2.0 support.
I'm tring to use MIDP 2.0 sockets without success. In the development
environment(Sun ONE Studio 5), everything seems to work but
when I download the midlet in the telephone and I launch it,
it blocks when it tries to open the socket:

SocketConnection sc =
(SocketConnection)Connector.open("socket://xxx.xxx.xxx.xxx:xx");

without throwing any exception.
If I open a HTTP connection (with HttpConnection class) to the same IP
address and port, it is correctly opened (but I can't use this
connection because the server doesn't support http).
Any suggestion? A gprs configuration problem?

Thanks

Gianluca
