NEW YORK -
Owners of Sidekick phones, made by a Microsoft subsidiary and sold by T-Mobile USA, may have lost all the personal data they stored on the phone, including contact numbers.
The companies say the data is "almost certainly" gone after a failure of servers operated by Microsoft wiped out the data. The companies said they hoped to update customers on recovery efforts Monday.
The phones have been troubled by data outages for more than a week. Some users attempted to restart their phones by removing the battery, which erases data on the device. Normally, the data is then restored from servers, but with the server data gone, the device is left empty.
