Q: Speeding up the iPhone

double tap your home button and then hold down a applicaiton in tell it shakes then hit the minus sign on all of those apps. those are alll apps running on your phone at that time

Leave more space (GB) in iPhone.

Do a reset (Hold Sleep/Wake and Home buttons about 10 secs or more till Apple logo appears, ignore the Slide to Power Off that appears)

Note: You will not lose any data.

No, those apps are not all running. They are recently used apps. Very few apps actually run in the background. Closing these non-running apps will do nothing to speed up the phone.

This is a myth. Only navigation and some music apps run in the background.

I have at least 18 apps in my multitask-bar everyday.

For the 4s it also helps to remove the SIM PIN from you SIM card. God only knows, why this works!

The last time I counted, I had 82.

Soon you end up in Guiness Book of Records.

How do you remove the Sim pin?

As your post is completely unrelated to the original post, you should start your own thread with a properly descriptive subject line. You're more likely to get the help you need and it's more polite.

Best of luck.

If removing the  sim pin speeds up the idevice I'd think it's more on topic then your post. Best of luck to you. Get a life. :)
