Is there a way to add more ram through the onboard sd card. I think this phone is great other than the limited amount of ram. If we could up the ram say to 512 or even 1 gig i think it would take care of alot of lag issues we have with tf3d. I know in win7, if i insert an sd card it will ask me if i want to add the Sd memory to speed up the system. So is it just a programing issue thats stopping us from doing this or is it a hardware issue?
