I have problem with sync client in Nokia N96 and Nokia 6220, when using GMS3 beta. Client installation is ok, but when it tries to start application I'll get KERN-EXEC 3 error. I have tried to hard reset mobile and I have updated the latest available firmware to N96 (11.101). GMS3 server works ok for my Nokia E51.

Nokia 6220 works with GMS2
Nokia N96 wont work at all (GMS2 or GMS3 beta)
