Fast SIM cards loosing bytes

Hi, I see earlier in the archives that reducing the buffer size in the firmware will resolve this. Hasn't this already been done though in new releases of the firmware? As I have pulled the latest version from the openpcd git repo and built it. If not what have people reduced the buffer size to? And has it had any fixes? Sent from my iPad
