I was updating my blog before and included a simplified howto, sorry for late reply.
oh, u r rite. I didnt notice the tray until u mentioned it, coz i just got my tablet for more than a week's time, and then busy to root it, testing the roms and problems fixing
Anyway, its a matter of time when there will be a guy come out with the mod coz like many of you guys, a roll back to phone ui really upset me
However, i have to say goodbye to my tablet z. I love it but it is just not the right device for me. I prepared to work on those missing mods, tweaks etc that i think the tablet z needs and deserve to have before but finally i find myself difficult to live with this tablet for personal reasons
This is a nice tablet actually, but didnt draw much attention as other sony devices
