In regards to ActiveSync, that is a vital program for XP SP3 as it allows you to use the USB for tethering for Cricket Huawei Android devices for accessing the internet, as well as data transfer to the Android platform such as installing programs and updates. Just tweak the settings to allow USB connections and connect to the internet and you are set. It seems to have taken the place of the native Android tethering programs that used to work in XP SP2, but now won't work in XP SP3. The Huawei Android native tethering still seems to work in Vista however, (so far).
