yes you can ... new post in development with autoflash ... will flash your arc/arc s with ics beta 4.03 .... its great ,works great ,but you need unlock bootloader
you can try it. Bugs are very minimum and fixable
I have it now and would recommend you to wait... It is quite slow at times... But if you can live with it then give it a go.. I use the Xperia mod and it is great
