Fastest Route from 3.02 -> Best

Hi all,

Is it worth updating to the latest firmware? And if so (which I'm hoping it will be), which version?

I'm still running 3.02 OE-B from a while back, and was wondering how far things have developed. It seems I can start by going to 3.52M33...

Thanks in advance!

first step would be make a pandora battery/memorystick with despertar cementario 5 then install 3.90m33 from pandora :)
