Does the first iphone use ios5?

Nope.3.1.5 or something like that is the highest

No.

The original ('first') iPhone's last supported Operating System version is iOS 3.1.3/7E18

The only devices that support iOS 5 are: iPod Touch (3rd and 4th Gen), iPhone (3GS, 4, and 4S), and iPad (1st, 2nd, and 3rd Gen)

Sorry but no. Apple wants to make you buy the newest phone to get the newest OS. The highest you can get for the original iPhone is 3.1.3 The phones that can go to iOS 5 are iPhones: 3GS, 4, and 4S. Best answer please. Hope this helps, good luck: D

Nope & neither does the 2nd.iOS 3.1.3 is as far as that one goes & the 2nd goes to 4.2.1.
