I have iPhone 3gs 16 GB on which i have 9GB space free but still it respond so slow. I am running on iOS 4.1. Tried cleaning the multitasking tray and clearing cache of browser but nothing happened. Is there any solution other then restoring?
Try a hard reset. Press the home button and the power button at the same time. Ignore the slide to power off and let go when you see the Apple logo. I also recommend rebooting daily to keep it running optimally.
You could try restoring. The 3GS is two and a half years old. The processor isn't the greatest and jailbreaking adds a little lag to it. The iPhone 4S is significantly faster. Have you considered upgrading?
4.0 and 4.1 were kinda bad for the iPhone 3GS maybe you could try upgrading, my 3GS is up to date w/the latest upgrade and it doesn't lag at all. I'm not jailbroken though so the software is all stock on mine.
I think so it is happen for using iOS 4.1. iPhone is works slowly with iOS 4.It doesn't work as smooth as it used to be. Also new applications such as the iBook application are very slow, doesn't respond smooth on screentaps etc.
You should going back to version 3.1.3 because IOS4 doesn't add anything to improve the user experience on the iPhone 3G.
IOS 4.1 hosed my 3G. I had to upgrade. Unless you knows someone who can restore the old operating system I don't know what to tell you. It helps a bit if you uncheck all of the options in spotlight search. Also, I improved things a bit on my 3 by doing a hard reset. You can try that too It helps some but you can't get it to be like it was.
