Hi there, I am using a black iPhone 4 running iOS 4.1. Recently, I have noticed that my iPhone is really laggy, particularly when I try to load something or try to watch a video using YouTube app. My iPhone loads like three times slower than other iPhones. Is there a way to speed up this phone?

On the other hand, you can also hard reset your iPhone. To do that, just simply press the Home button and the Power button at the same time until the iPhone shuts itself off and begins to restart. Then release both buttons when you see the silver Apple logo on your screen. You should be noted that this will take a little longer to boot than the normal boot.
Lastly, since you are on an old iPhone firmware, restoring your iPhone to the latest iPhone firmware available will definitely fix this issue. To restore, all you have to do is connect your iPhone to your Mac or PC, launch iTunes 10.5 and then select Summary and Restore option.
Note: Please do not forget to backup all your data first before restoring to iOS 5 firmware.
