"iPhone 4s or higher?" Which iPhones could I buy?

[Whitney Gabriel]

Hi! I'm applying for a new job that says I need a "iPhone 4s or higher". I know that includes iPhone 5's but does it include iPhone 4? Or is the iPhone 4 lower than the iPhone 4s?

Thank you!

I realize that this is a bit late, but what kind of job requires you to bring your own device and specifies the brand ? Normally I'd expect the employer to provide the phone or reimburse you for the use of your own phone, but in the latter case they don't get to tell you what to buy.
