Nival1 Обновляешься через диспетчер устройств я так понимаю. А ты попробуй через обновление ПО. Или в параметрах профели сервера убрать если какие нибудь есть, у меня просто ни одного там нет и нормально работает.
Вот нашел изменения, но это вроде не полный список. MfE client update, fixes for both HTML error message and special character related problems in some environment. There's also some changes which reduce the amount of time which is spent during sync. The biggest thing is that this client update will also reduce the current consumption of the device significantly. I suggest that you enable the "always on" option for sync and see for yourselves. Of course the current consumption with other options (15min / 30min etc) are also improved. Other things, like the accidental keypress filter have been improved which speeds up the SMS / email writing with QWERTY, GPS problems have been fixed, some VoIP and WLAN specific improvements etc.
