While iOS 11.3 doesn't need as much free space to install as some of the earlier releases of iOS, getting rid of apps that you no longer use - or perhaps have never used - makes good sense. You ignore backups at your peril! Spring clean your iPhone or iPadĬhances are that your iPhone or iPad has accumulated a lot of detritus over the months and years, so what better time to get rid of it than now.

Keep in mind that unless you're willing to jump through hoops and do things that Apple frowns upon, going to iOS 11.3 is a one-way trip, so you might want to let other people to go ahead of you just in case there are gotchas. You can either create a local backup using iTunes or backup to iCloud by going to Settings > iCloud > Backup, and then turning on iCloud Backup. Plenty of iOS launches have been marred by bugs and problems, so with that in mind, it's a good idea to have an up-to-date backup, because making a fuss isn't going to bring back your lost photos or documents. Things can go wrong, stuff may be broken, and you may lose data.

Remember that things can - and do - go wrong!īefore you go hog-wild, throw caution to the wind, and start upgrading, be aware that there are risks.
