Sadly I have not soldering ability
I'll wait to see if something positive happens for "fixed" (or broken by our point of view) devices... I suppose more and more people will buy PRS-T2 and then a solution will be found or Sony will realese PRS-T3 (or what they would like to call it) already fixed if they're not stupid and then there will be more incentives to found a solution that maybe would be valid for PRS-T2, too...
