GPS and GPRS moduleuse different baud rate

Hi,

I use Ublox NOE-6 GPS modul and a SIMCOM GSM shield in same time. I have a lot of problem because these two use different baud rate. NEO-6 only work with maximum 9600 but GSM doesn't send anything with 9600 and sometimes doesnot receive messages. It works correctly with 19200. Do you have gyus some suggestion in this case?
