Before you contact me consider a few things:

• Please read the FAQ. Most of your questions are already answered there. I will not answer questions which are already explained in the FAQ. Especially do not ask for SIM-unlock, release-dates or support of other models! I will try to support more models, but that is very dificult, so don't hold your breath.
• There are two instruction video's which demonstrate how to use the tool:
  Windows Phone Internals Introduction Video
  Create a Custom ROM with Root Access
• The tool has a "Getting started" section which explains many scenario's.
• Asking the community often results in faster results than asking me personally. You can add comments to the articles on this website or you can add a comment in the official XDA support thread.

As you can see, I spent a lot of energy in explaining everything about Windows Phone Internals. I'd like to concentrate on creating new hacks instead of answering questions I already explained. But if you have a very specific question for me, you can contact me here.
