BTW: Does anyone know about the differences between Gizmo for N800 and Gizmo for 770? The N800-version supports a 2nd SIP-account, the 770-version doesn't. But I could install the N800-version on a 770 without any problems. Why do they offer two versions for download if they seem to work independent of the hardware? Are there any known problems with the N800-version on a 770 that I simply didn't encounter yet? (I installed it only yesterday.)
