A member over on the Xda-Developers forum has figured out a way to get access to the registry of any HTC device running Windows Phone 7. The method allows the user to write their own registry values over the top of some preconfigured ones, such as accent colors.
We"ve written up a handy guide on how to change the accent colors on your own Windows Phone 7 device, in case you hated the stock colors as much as we did. The registry editing part of this trick is thanks to xda-developers forum member "xboxmod" and we take no responsibility for this process in the odd event that it bricks your phone (Don"t worry, it didn"t break ours).
1. To get started, be sure to have the HTC Connection Setup application installed already. This can be found under "HTC Apps" in the marketplace. You"ll also need a developer unlocked device, either using ChevronWP7 or the official developer unlock. Finally, install TouchXplorer onto your WP7.
2. Create three text files in notepad containing the registry keys found below. For this, we want to replace one of the existing themes -- pink -- with a nicer blue theme.
First file:
