In the Windows Phone Update 1 Preview, new Bluetooth profiles are supported in the latest OS update from Microsoft, giving consumers access to new abilities. Those new profiles included PAN (personal area network) 1.0 profile, aptX codec support for A2DP, and browsing support for AVRCP.
In regards to PAN, one visible area in which consumers can immediately see the difference is visible under Internet Sharing.
Previously, this section included a simple on / off toggle, along with the device name and password. However, with Update 1 rolling out today for those on the Preview program, you now get an additional section to choose how to share that connection, either through Wi-Fi or Bluetooth. As suspected, being able to share your internet connection through Bluetooth is the new differentiating factor from the previous 8.1 release. Although not nearly as fast or effective as Wi-Fi, being able to share over Bluetooth is useful for legacy devices and other specific-usage scenarios.
