I need help my iphone hang - Apple iPhone Smartphone

Do you have any other phone apps on your iPhone that may be telling it to keep the line open?

Plug it into your computer and open iTunes, select your iPod in the list to the left, under the big picture of your iPhone there's a button that says "Restore," this will do a restoration of the software on your iPhone. You might lose some saved text messages and such but it will fix your iPhone.
Hope this helps!

if yopu have too much files on the memory pls delete some,if it persist just flash in new memory and the hanging will be detected and it will be corrected.

press and hold the home button and the power button until the iphone reboots.

The best option is to force your phone into recovery mode and restore it via iTunes. Here's how to do that:
