A very annoying problem I encountered with my BlackJack II device is that the IE homepage is locked to a crappy ATT&T media net portal. There is no UI option to change it, and this is really aggrevating.
Anyway, I figured out how to change the home page to whatever I want, and thought I'd share with anyone else who might be as frustrated as I was.
First, download a Windows Mobile registry editor like the one found here: http://www.breaksoft.com/Blog/Utilities/2005/1/Mobile_Registry_Editor.aspx
Once you install the editor, connect your mobile device via USB cable and ensure you can establish an activesync connection.
Next, launch the editor and browse to HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\AboutURLs in the registry editor.
Update the \home and home_0409 keys to any URL you'd like.
I think Windows Mobile 6 is a great improvement over Windows Mobile 5, but I would like to understand the rationale for locking out the ability to change the home page URL on the BlackJack 2. I imagine it is an ATT&T tweak, and nothing to do with Windows Mobile 6, but if anyone has any insight here, I'd appreciate it.
