With the release of ActiveSync 4.0, mobile users everywhere suffered a great loss. Namely, you can no longer maintain a network connection while synced. This means that you can’t sync via WiFi or an Ethernet connection. According to Microsoft, they removed this useful feature because some corporate customers had thought it was a security risk. However, we believe that taking it out is a much greater risk[1].
The result of this feature removal is that any ActiveSync session (via Bluetooth, IR, or USB) will immediately disable your network connection. Our AirFix program will give the control back to you, which is where it belongs.
