I try to figure out whether the Xperia Arc has a gyroscope or not. After searching the web everywhere, I still can't conclude. Note that a 6-axis accelerometer or gyro (gyroscope) should be the same hardware-wise. But from my reading, I think your device needs to run Gingerbread for its gyro to be made available. Does anyone every tested his Xperia Arc (running Gingerbread) with some real application that make uses of the gyroscope? I would like to hear some actual facts from someone who really knows what he is talking about. Example of gyro-aware apps in the Application Market: Phone Tester Z-DeviceTest Gyroscope Rotate Ozo.
