T-Mobile and the Sidekick data services provider, Danger, a subsidiary of Microsoft, are reaching out to express our apologies regarding the recent Sidekick data service disruption. We appreciate your patience as Microsoft/Danger continues to work on maintaining platform stability, and restoring all services for our Sidekick customers.(Emphasis, mine)
Regrettably, based on Microsoft/Danger's latest recovery assessment of their systems, we must now inform you that personal information stored on your device - such as contacts, calendar entries, to-do lists or photos - that is no longer on your Sidekick almost certainly has been lost as a result of a server failure at Microsoft/Danger.
I know that service disruptions happen al the time - that's why I rely on Lotus Notes. I rarely see them. As far as T-Mobile and Microsoft spinning this, I would classify this as a little more than a "disruptuon" and a lot more than an "inconvenience".
