Itead 3Gshield

Hi fellows,

I have a few of these shields to build a telemetry project at work for SMS alarm reporting and sending some data on a web page.

SMS work great, the shields are on top of arduino Unos and it work fine, only i just can't open a TCP/UDP or HTTP socket, it seems that the

AT+CGSOCKCONT=1,''IP'',''apn''

don't work for me
