Can a Sony Ericsson Xperia X8 download the Uber app?

According to the description in the Google Play Store,your operation system needs to be at least Android 4.0.3
From a bit of Googling,the last official Android version for your phone was at Android 2.1

If you're running a custom/aftermarket version of Android 4.0.3 or higher,the app should work.

If that's not an option,just use your phone's browser to log-in to Uber & you should have no problem with using their service.
