I recently got ahold of my grandparent's iPhone 5s, who wanted to upgrade to the bigger one. After erasing and cleaning it up, I found out that the iOS was never updated, staying put on 7.1.1 after all these years. Considering this isn't exactly a common occurrence, I'm wondering what I should do with this iPhone 5s on iOS 7.1.1. Particularly, what would YOU do? Would you jailbreak it? Would you switch to it as your main device? Do you find anything special about iOS 7 that you can't do on newer firmware?
