iPhone 4 lags - hangs

[ixodes]

My iPhone 4 with iOS 4.3.2, has become slow to respond in some instances. When going into settings, upon making changes like turning off WiFi, then clicking on the settings button on top to return to the main settings page, it is unresponsive (it hangs) for as much as a minute before it returns as it should.

I've reset the phone to no avail.

Advice please?

I'd suggest upgrading to iOS 5 on your iPhone. i felt some speed improvements when I upgraded on my 3GS, so I'm sure youd get some too.

Also, do you have a lot of apps open on the phone? You can close running apps by double pressing the home button and holding down on the app to free it from the memory.

Double click the home button, and touch and hold one of the icons until it wiggles. Then go through and tap the little red X. It won't delete the app, just remove it from the memory.
