My novel Android Smartphone Star X18i (ordered from that particular shop), running Android 2.3.4, has been rooted using the instructions in this thread: http://forum.xda-developers.com/showthread.php?p=18615502#post8615502 (method 2b, using the zergRush exploit, v3). Nice work for the script, I just copied the instructions step-by-step. The phone itself seems to be a Sony Xperia X10 clone.
