Hi, I have been having trouble recently with my 3GS running low on memory and getting sluggish. It got so bad yesterday, that I was playing music in the iPod app and trying to switch to check Twitter that the music started skipping. Lasted like 15 seconds until I finally got the Twitter app closed. According to SBSettings, when I reboot, I have ~135MB free. As I use apps, the memory gets lower and lower until it stays pretty consistent in the 10-15MB area. Occasionally it actually drops below 10. When that happens, I can tell the phone gets really slow and unresponsive. It's like the OS is not closing unused apps soon enough or freeing up memory. I had been using biteSMS and thought maybe that was a culprit since it was running in the background, so I went into Cydia and removed it. It seemed to work a little better, but eventually it got down to the 12MB area and stayed there. Anyone have any ideas to what might be causing this?
