Since the device has the almost standard 800x480 resolution you can, unlike the X10i, use almost all boot animations found online.
Since the Test 3.1 custom rom has no boot animation and I happen to play a lot of Fallout lately I made a boot animation from a Pip-Boy 3000 boot screen I found online:
Just copy the zip file to the /system/media/ folder on your device (make sure you set the permissions correctly afterwards). If you are also using the test rom you have to remove or comment (with a #) the following line in the build.prop file (which is located in the /system/ folder):
| debug.sf.nobootanimation=1 |
