I've considered that, but the last time I tried you couldn't use the words iPhone or iPad in a Google Ad. Has that restriction gone away, or how do you work around it?

You can use those terms if you get permission from Apple. I can't remember the email address offhand, but there is one you can contact for approval.

wouldn't iOS be a better term anyway?

Highly depends on the market. If you're aimed at tech geeks, maybe, but I'd guess that your average iPhone/iPad user doesn't really know what iOS is unless they've jailbroken.
