1/ Change your iDevice name — If your iPhone (or iPad) calls itself ‘iPhone’ instead of ‘[Name]’s iPhone,’ it’s not really a problem until you can’t find it and you’re having to shuffle through approximately thirty poorly named devices on the Find My iPhone app or on iCloud.com to try to find its location.
To change this on the iPhone or iPad, visit Settings>General>About. You can edit your device’s name at the very top (and while you’re there, you can also see all sorts of stats about what’s taking up your space). Once you update that info, iCloud.com (and the Find My iPhone app) will reflect the change within a few minutes.
(On Mac, you can do this too, in System Preferences>Sharing. At the top of that pane, there’s a box for you to type into.)
2/ Block annoying people phoning you — There’s a simple way to block any number from contacting you in iOS. To do this in the Phone app, tap the ‘i’ next to the caller’s number under the ‘Recents’ tab or the ‘Voicemail’ one, then scroll to the bottom of the following screen and tap ‘Block this Caller.’
Your device will warn you of what you’re about to do.
3/ Block messages — You can block someone in the Messages app too –tap on the ‘Details’ button within the conversation, find that familiar ‘i’ (for Information) on the next screen, tap that, and choose ‘Block this Caller’ in the same way as above. Again, your device will warn you of what you’re about to do.
You can see everyone you’ve blocked under Settings>Phone, Settings>Messages, and Settings>FaceTime (they all reference the same list). If you tap ‘Blocked’ in any of those places, you can remove a caller from your naughty list or add a new offender manually.
Note that your phone won’t ring when a blocked number calls, but the caller can still leave a message; however, since you won’t get a notification or anything, you won’t know a voicemail has arrived unless you check. The place to do that is within the Phone app under ‘Voicemail’ at the very bottom of the list, assuming your cell phone provider sports Voicemail.
4/ Backups take up space — If you’ve ever backed up your devices to iTunes (which I prefer to iCloud backups since my Mac is, in turn, backed up via Time Machine), it’s important to know those old backups may still live on your computer, and they could be taking up a ton of space, particularly if you have a space-challenged MacBook air, for example.
Check it out – open iTunes and then choose iTunes>Preferences from the iTunes menu at the top. When the Preferences window opens, choose the Devices tab. If you several backups in there, some may be for devices you no longer even have. Select one and click the Delete Backup button…
5/ Other settings — There are a other things you can do within this Preferences>Devices dialogue box (above). Right- or Control-click on a certain backup to see some handy options. For example, you could archive the backup to another device before deleting it. This creates date-stamped snapshots.
Show in Finder can be used along with Finder’s Get Info command to determine how big the backup in question is.
One more nifty thing you can do within Preferences>Devices is hover your cursor over any of the backups to see some information about the device it was made from (like, say, the serial number).
