T-Mobile and Microsoft are trying to get your data back.

If they can't here's $100 and a month of free internet on your phone.

Remember last week, a server crashed and took names, numbers, pictures and appointments with it.  Some Sidekicks are slowly remembering contacts and calendars.  And some are not.

So T-Mobile is sending a $100 gift card to those phones affected by the outage.  That money can go toward your monthly phone bill or any other service T-Mobile offers.  That's on top of a free month of data service.

If you don't want to bank on T-Mobile recovering the information, you can try to get it back on your own.  T-Mobile has a step-by-step instruction guide to getting your phone to remember your contacts.
