You can drag multiple apps at once in iOS, which can make organizing a much quicker process. Instead of tapping and dragging apps one by one into a folder, you can stack many of them and drag the stack. To do this, long press an app until it "wiggles," then start to drag it somewhere. While still holding onto it, tap another app that you want to stack and it will automatically add to your stack. After the second one, you have to double tap any additional apps to add them to your stack. A number will appear on the top icon indicating how many items you have in the stack.
You can easily find your iPhone serial number (S/N), International Mobile Equipment Identity (IMEI) number, and identifier or ICCID. Follow these steps to get this information:
If your iPhone is functioning properly:
1. Navigate to Settings -> General -> About
2. Scroll down
3. The Serial Number, IMEI and ICCID are listed along with other information.
If your iPhone will not turn on or boot properly:
Your serial number and IMEI are both printed on the barcode label that's affixed to your iPhone packaging.
If you don't have your iPhone packaging:
iOS 7 is packed with new features and a completely redesigned appearance. You may have noticed that over time, some apps on the home screen or inside folders gain a blue dot to the left of the app name. What does this blue dot mean?
If there's a cloud symbol next to an iOS app name, this app has been offloaded to increase storage space on your device.
