iPhone Tip: How to Close Multitasking Apps on iOS 4

July 22, 2010 — by Simon Ng8


How can I close the apps running in background via multitasking dock? Are all apps displayed in the dock running in background? Since the launch of iOS 4.0, I have received these questions from my friends and some of the blog readers. So I think it is better to write a blog post to share the procedures with all of you.

The multitasking feature is the most notable update for iOS 4.0. As you may know, you can double press the Home button to bring up a multitasking dock that shows all those apps running in background. You can simply tap on any of the app icons and switch to your desired app instantly.

If you are not using an official SIM (say, the one from AT&T), you should be very familiar with the below message shown in iTunes when you connect the iPhone to your computer:

The SIM card inserted in this iPhone does not appear to be supported.

June 28, 2010 — by Simon Ng26


After I published the post about PwnageTool for iOS4 jailbreak, one frequently-asked question that has been raised by many readers is:

For those who do not read the article about PwnageTool, you may wonder why we need to know the bootrom version.

So if you are using iPhone 3GS, before jailbreaking iOS4 with PwnageTool, the very first step is to determine whether your iPhone is using the old or new bootrom.
