Thank you for writing Xbox Customer Support!
I'm sorry for the inconvenience if it is not yet compatible with Xbox 360. But don't worry, we have a team of some of the best developers at Microsoft dedicated to working on this. They are currently working on on it. We're not announcing any dates, because we honestly don't know how long it's going to take to do the next update.
Please check the website,
http://www.xbox.com, for any future updates. Thank you for understanding.
You can give feedback or suggestions to the team by sending an e-mail to
backcomp@microsoft.com. We read every e-mail sent to this address.
Your feedback makes a difference! We value your feedback and use it to help us identify issues and prioritize our next round of titles. We're sorry that we aren't able to reply to everyone directly.
For further assistance, please don't hesitate to write back or call Xbox Phone Support at 1-800-4MYXBOX (1-800-469-9269) at your earliest convenience. We are open everyday from 9am to 1am EST/ 6am to 10pm PST.
To expedite service, please provide Service Request Number 1********4 when you call.
Good News! You may link your console to your Windows Live ID, and check repair status online at the web site:
