It was just a few days ago, that Sony Ericsson released details on how to unlock the Xperia Arc, Play and Neo handsets boot loader.
Now, in just a matter of days the talented developers over at XDA forums have managed to get root access on all the above said handsets.
The method to get root access is a pretty simple one Users first need to unlock their boot loader, and then flash some required files using fast boot. However, at the moment this method works only on the UK firmware of the Arc and the Play.
The developers behind gaining the root access Bin4ry and zdzihu are already working on rooting the global firmware.
Hopefully, Sony Ericsson will soon release the Android 2.3 Gingerbread source for the the latest bunch of the Xperia handsets. This will help the developers in cooking custom ROMs for the Xperia Arc, Neo and Play.
