GUIDE: Windows Mobile 5 and 6 - enabling DUN

From Internet Tablet Talk

Why DUN doesn't work

Microsoft decided in WM5 AKU3 (an update to Windows Mobile 5) to remove DUN in favor of Bluetooth ICS (Internet Connection Sharing.)

This is a generally good move: it means that the phone turns in to a small Bluetooth router, which several devices can connect to. There are several other perks to this method. Read http://blogs.msdn.com/windowsmobile/archive/2007/04/17/why-did-we-remove-bluetooth-dun.aspx if you're interested in the reasons.

The downside, however, is that the tablets do not support Bluetooth networking out of the box.

The Easy Fix

http://forum.xda-developers.com/showthread.php?p=1400709 details a hack that will re-enable DUN on most WM5AKU3/WM6 PDAs.

At this point, please visit either GUIDE: Everything about CDMA-like Providers (Verizon, Sprint) and DUN or GUIDE: Everything about GSM Providers (T-Mobile, Cingular) and DUN for the next steps.

The Hard Fix

Start with HOWTO:_Connect_to_the_Internet_using_Bluetooth_via_a_Windows_PC.

A more specific article will be added later: what you need to know is that your phone, when Bluetooth ICS is on, becomes a Bluetooth access point. Skip the configuration on the Windows side, other than turning on Bluetooth ICS, but do pair your phone and PDA together.

EDITOR'S NOTE: It appears that page is missing the last half as of this writing. I'll try to piece together a guide from the instructions on the old site, but I don't have a Windows Mobile phone to test with. --Aleksandyr 15:24, 19 January 2008 (EST)
