I bought one of them. The phone is basically unusable, because touchscreen doesn't work correctly. The seller wrote me that an updated firmware should fix it. But to update the firmware I had to purchase a special cable. I tried the update yesterday but it didn't work. I have to ask them what am I doing wrong.
All support is only on Chinese forums, the phone has many dialogs in Chinese and it is very slow (only 460 MHz CPU, no 3D acceleration).
So I wouldn't recommend it. Although you might be lucky and get a better phone then I have.
