32. Update apps automatically
iOS 7 now has the ability to update your apps automatically, so you don't have to do it manually. It can also automatically download new purchases that have been made on other devices associated with your Apple ID.
In order to turn this feature on, you'll need to go to Settings > iTunes & App Store and then scroll down to Automatic Downloads. Here, you can choose to allow automatic downloads of new music, apps and books, and can also turn on the automatic download of updates. Additionally, if you're happy to use your internet data allowance for this feature, which we wouldn't recommend unless your allowance is unlimited, you can turn on the Use Cellular Data option.
33. Add apps and music to your Wish List
When you're browsing the App Store or iTunes Store on your device, you might come across something that you want to download later. Now, you can add these items to your Wish List.
To do so, go to the app or music you want to add and then tap the share icon in the bar along the top. From here, you can tap Add to Wish List.
When you want to look at what's in your Wish List later, you just need to tap the far right icon in the top bar and tap Wish List.
34. Use Siri to toggle settings
Siri can do more than ever in iOS 7. The voice-activated assistant can now toggle system-wide settings for you, and open the Settings menu for a particular app or command.
You can now tell Siri to "Turn on Bluetooth" for example, or from within an app, you can say "launch settings" to alter the settings yourself.
35. Use Siri to find out what's Trending on Twitter
Siri also has much closer integration with Twitter. You can ask: "What's trending on Twitter" and it'll tell you.
You can also ask what someone is saying on Twitter to see their recent tweets, or search Twitter hash tags, too.
36. Change search engine in Siri
Siri's default search engine is now Microsoft's Bing. So if you tell Siri to search the web, it'll do so via Bing.
If you don't want to search Bing, you can tell Siri to "Search Google for Macworld," or "Search Wikipedia for Macworld" for example.
37. Change search engine in Safari
You can also change the search engine in Safari if you want to. To do this, go to Settings > Safari > Search Engine and choose between Google, Yahoo and Bing.
38. Remove a contact from recents in email
When you create a new email in iOS 7, typing in the first letter of a recipient will bring up a list of people you've recently emailed. You can remove a contact from the recents list by tapping the 'i' next to their name and then choosing Remove From Recents.
39. Open a new tab in Safari
With the Safari improvements comes a new tabs system. You can open up to 24 tabs, or pages, in the Safari app. To access them, you'll need to tap the square icon in the bottom right corner of the screen.
You'll then see a scrollable 3D view of your tabs. To open a new one, tap the plus button in the centre of the bottom of the screen. You can also open a link in a new tab by tapping and holding on that link and selecting the "Open in New Page" option.
40. Close a tab in Safari
After tapping the square icon to bring up the view of your tabs, you can close tabs by tapping the cross button.
