List of features removed from Windows Phone 7

While Windows Phone contains many new features, a number of capabilities and certain programs that were a part of previous versions up to Windows Mobile 6.5 were removed or changed.

The following is a list of features which were present in Windows Mobile 6.5 but were removed in Windows Phone 7.0.

Storage

 * Windows Phone 7 supports upgradable storage via an SD Card; however SD card memory is merged with the phone's internal storage, and changing the SD card causes the phone to reset to factory settings,
 * USB mass-storage,
 * System-wide file manager.

Connectivity

 * Windows Phone 7 does not support connecting to Wi-Fi (wireless) access points which are hidden and protected with WPA,
 * Connecting to Wi-Fi networks that have a static IP address,
 * Tethering to a computer (although it can be done via a hack on the Samsung Focus ; can share 3G connection over WiFi ),
 * Bluetooth file transfers,

Calling

 * Videocalling,
 * VoIP calling,
 * The list of past phone calls is now a single list, and cannot be separated into inbound, outbound or missed calls.

Sync

 * Doesn't support usual USB sync with Microsoft Outlook's Contacts, Tasks and Notes as opposed to older versions of Windows Mobile with Desktop ActiveSync. Syncing Contacts and Appointments is done via a cloud-based service (Windows Live, Google, or Exchange ActiveSync) only. There's no way to sync this personal information directly from a computer to a windows phone and back.

Enterprise

 * Windows Phone 7 does not support Office documents with security permissions,
 * IPsec security (VPN),
 * On-device encryption,
