Odd, the guide i followed must be for a similar module but not this exact one then, and that would explain a lot 
Here's a picture of the module, the jumpers etc:

Thank you for that link, don't know why i followed the Libelium guide in the first place since i bought the module from cooking-hacks. But i'm afraid none of the tips helped, can't get any reponse from the board at all.
I've put the jumpers in the right position, followed the guide accordingly.
The only thing i haven't done is solder (or just put) a 220µF capacitor on the 5V and GND because i have a external powersupply that generate "enought" power what i thought.
Edit: Here's my CuteCom settings and output after sending a AT+[CRLF] command.
