But, what will you do with your old one?
Apple is expected to announce the latest model in its ground-breaking smartphone line today.
Here are some suggestions about what do with the old iPhone.
Give it to your kids so they stop taking yours -- or maybe to your folks.
You can donate the phone to charity.
You could use it as a spare camera or GPS navigation unit.
The old iPhone could also be worth some cold, hard cash.
Or Apple will give you up to $280 in credit for trading in an iPhone 4s that's still in good condition.
