Microsoft has confirmed data recovery for Sidekick users, in this post on the Microsoft web site:
Dear T-Mobile Sidekick customers,
On behalf of Microsoft, I want to apologize for the recent problems with the Sidekick service and give you an update on the steps we have taken to resolve these problems.
We are pleased to report that we have recovered most, if not all, customer data for those Sidekick customers whose data was affected by the recent outage.
We plan to begin restoring users’ personal data as soon as possible, starting with personal contacts, after we have validated the data and our restoration plan. We will then continue to work around the clock to restore data to all affected users, including calendar, notes, tasks, photographs and high scores, as quickly as possible.
We now believe that data loss affected a minority of Sidekick users. If your Sidekick account was among those affected, please continue to log into the T-Mobile Sidekick forum at www.t-mobile.com/sidekick for the latest updates about when data restoration will begin, and any steps you may need to take. We will work with T-Mobile to post the next update on data restoration timing no later than Saturday.
We have determined that the outage was caused by a system failure that created data loss in the core database and the back-up. We rebuilt the system component by component, recovering data along the way.
Sincerely,
Roz Ho
Corporate Vice President
Premium Mobile Experiences, Microsoft Corporation
A number of lawsuits have been filed, says C/Net, including two filed in federal court in Northern California on Wednesday that allege both negligence and false claims on the part of Microsoft and T-Mobile.
