Almost everything. I install all into the card unless explicitly stated to be on the main memory. Including panels.
But I never remove the card from the phone, if you change it, it may give you troubles.
well, some say to put panels not on the card, and many do not state where to put the new software....? and, also, very often, when installing a software, I am running into troubles, with the X1,and it would be nice, if the file would say, put it here screen resolution minimum....and if for wm5 or wm6....
for example I did installed the Touch it blackstone manila hd full on my card, and can not see it nowhere...?
sorry
