Mobile phone stores in the United Kingdom pulled out their Sony Ericsson Satio display due to a software bug that causes the device to power down unexpectedly. When users try to access certain applications, the phone reboots, a problem that apparently cannot be fixed with an over-the-air update. Sony Ericsson Senior Marketing Manager Richard Dorman confirmed with the publication that it is a known issue and that the manufacturer hopes to solve the problem by Christmas.
