Video chat apps for iPhone 3 that don't require front camera?

Me and my long distance girlfriend want to talk to each other, but can't use Skype yet because we have to keep our relationship secret. Is there any live video chat apps I can use to talk to her? Oovoo is a possibility because it doesn't require a front camera.

You have to go to the technology section and post there.

And the answer is no, there's no app for that. You either do skype or facetime or you don't video chat.
