T-Mobile this Saturday has issued a warning to all Sidekick owners that their online data may have been permanently lost by Danger and its parent company Microsoft. In a note to customers, the carrier says the likelihood of recovering contacts, calendars and other information taken offline by a more than week-long outage is "extremely low" due to an assessment of the server failure. Customers may lose all their information if they have to reset their sidekicks or deprive them of power, according to the note.
