This has been hashed over and over. There must be 10 similar thread on this forum so not sure why people see the need to open yet another one, but.
Nothing actually fully fixes the GPS issue in HTC honeycomb, same for all the custom HC variants. It appears to have a problem that repeatedly resets the GPS after a period of time. For some applications, it will still work if you are in a location that allows a fast lock again or for applications that need a one time fix. There is something buried deep in the driver or kernel that is playing havoc with the GPS.
STILL NOT FIXED ON ANY VARIANT OF HC.
