T-Mobile said late on Monday that it may yet be able to recover Sidekick users' information that it had previously thought was lost as part of a massive server failure by Microsoft's Danger subsidiary.
"Recent efforts indicate the prospects of recovering some lost content may now be possible," it said.
Those who do suffer permanent data loss will get a US$100 "customer appreciation card" good toward T-Mobile service or products, the carrier said in a statement.
"For those who fall into this category, details will be sent out in the next 14 days--there is no action needed on the part of these customers," T-Mobile said. "We however remain hopeful that for the majority of our customers, personal content can be recovered."
That marks a significant change in tone. Last week, the carrier and Microsoft had warned that any data not on a customer's phone at that point was likely gone forever.
Monday's business day came and went with little public comment from the companies, but apparently efforts to restore data were more fruitful.
T-Mobile did halt sales of the Sidekick as it investigated the issue.
T-Mobile continued to urge customers not to remove the battery on the device, reset the Sidekick or let it run out of power while the company works to restore its servers.
