thanks for your help man I installed gingerbread Nitdroid 0.0.9 on emmc....all is good, but I downloaded some apps and lot of them crashing...somewhere here I find a list of progs that are supposed to be working ...but here a guy said that every downloaded program should be working. what's the true? And about that sudo mambo thing in x terminal....for a windows user like me I do not find a good tutorial vhith examples...only links for linux pages, where u find commands that are not compatible Anyway ...learning...learning
