RootingCopy the above files in your SD card files are named upd_1.zip (for rooting) and unroot.zip (for unrooting).Switch off phone and restart in Android System Recovery mode i.e press and hold Menu+Power keys till it reboots in recovery.Go to "apply update from sd card" and select upd_1.zip. The process will be completed soon.Restart your system. You have successfully rooted your phone. In my case I got a Force close of application once but do not worry about it.
