I have the 3GS and I noticed that it slows down a bit and the RAM ( i think that's what it is ) at the top said something like 60 MB. I deleted alot of stuff, even Lockinfo and right now its at 142, highest I've seen is 160. I think its advertised as having 250 MB. I just want to know if this is normal, and what's the average RAM it usually has going on while everything is running in the background.
