It seems that the newly released high-end Palm Pre is set to periodically send end-user data to Palm, as Joey Hess, a Debian developer, points out. According to him, the data sent to the handset maker includes GPS location, what applications are installed on the device, what apps are used and for how long, and crash logs. For what it's worth, it was somehow expected for the device to send data back to the company, mainly due to the fact that some of these pieces of information might help the company improve its services.
We should also mention the fact that the Pre is not the only handset that sends info to the manufacturer or to the carrier. While operators are known to log some of the subscribers' actions while browsing the Internet, for example, as one user responds to Joey Hess' post, some of the applications that run on different devices do the same thing. Most often these details indeed help companies bring improvements to different aspects of their services, so it’s all for a good cause in the end.
