GPRS Shield Baudrate Issue

[slax01]

Hello World!
Yesterday I was playing around with my GPRS shield and changed the baudrate of the software serial to 115200. Since then I have not been able to get the serial to work, even by using the same baudrate in my arduino sketch for communicating with the shield, therefore I am not able to fix this or do anything with the shield at all. Any ideas on how to fix this? Any way of resetting/erasing the non-volatile memory of the shield so that the default configuration is restored?
Thank you for your time guys!
