Do you have alot of apps installed? You may be low on usable disk space.

I agree with cpjr, if you have alot of apps installed then your applications partition has probably run out of space, so youll want to uninstall a few apps and download bosstool from bigboss and then move fonts, then ringtones, then apps to the media partition so that you have more space available. Youll want to make sure you media partition has plenty of space as well.

A little more information would be helpful, like when this started happening and that sort of thing.

Otherwise you may need to do a restore.

Restore your Iphone in itunes.

Once it is restored. Notice how amazing the speed is. The responsiveness.

3rd Party apps slow down your Iphone a lot. Especially when you have themes installed.

I recommend that you restore your iPhone and start again.
