Def need more then one RAM I hate having to close programs down cause the device becomes slow cause of the lack of RAM
hahaha. oh jeeze. nobody told, you, huh? you dont need to close programs to "speed up" your iphone. thats an absolute myth. the system auto-suspends background apps w/ the exception of music/location processes. your manual closing does absolutely nothing except make you feel better.
but dont take it from me. take it from people who know more than you do:
