i started up my ipod touch and on sbsettings and also through memory doctor, it says i only only have 122 mb free memory. i did nt even install many things or substrates, i just go tmy ipod touch 4g a week ago. people on here are saying they have 160mb free upon startup. how is that possible? i mean i get like 20 extra mb if i use "Free memory" option on sbsettings but is there a way to get extra free memory upon startup so i don't have to resort to sbsettings everytime? what launch daemon do u recommend that i delete?
