Next year I better open some CC spend some money towards iphones, get 400-500 bonus dollars and close it.
These days you're just as well to keep the card(s) open and use them once a year to keep them alive. Many credit scores/decisions are based on percentage of total available credit in use. So the more unused credit available the better off you are.
What you definitely do NOT want to do is close your old credit cards; the older your active accounts the better. I keep a couple cards around that I'd originally opened twenty years ago even though I primarily use other cards (such as Citi's 2% cash back).

The above of course assumes one has the discipline to have a pile of available credit and not spend it.
