The carrier-specific versions of the Xperia X10 might be considered on a case-by-case basis. Sony Ericsson confirmed that the sudden change of heart was due to the overwhelming demand for this update, and the work the company already did to install Android 2.3.3 Gingerbread on its upcoming Sony Ericsson Xperia arc, Xperia Play and Xperia neo phones.
Good news for the Sony Ericsson Xperia 10 owners, but some functionality, like face recognition for the camera, might be lost in the process. Mediscape will also be replaced by the new media and music player widgets (check them in our preview here). The Xperia X10 will be the only one receiving the Gingerbread update from SE's 2010 crop of Android handsets, and this will be the last update for it, whereas this year's phones will continue getting whatever Google has in store for the next Android versions.
