You could and still can do both from your carrier, it's pretty standard. In my experience, it's somewhat uncommon for people to actually buy their phones outright unless you make a lot of money (like the folks who tend to frequent HN). Every two years, my wife and I would sign up for a new 24-month contract, which would include two new phones. After those 24 months, we could keep paying off the remainder of the phones and keep them, or we could return them and start a new contract with new phones.

Myself and my family did, for sure. My parents made me pay my own phone bill too, so I spent a long time in the Alltel shop staring at the different phones and probably annoying the clerk.
