Can you still test iPhone applications on an iPhone without a cell carrier?

I'm about to start doing some iPhone application development and it's important to me to be able to test my applications on actual devices before I put them on the marketplace. However, I am planning on switching from AT&T to Verizon soon due largely to the cost of my current plan.

If I discontinue my AT&T service but keep my iPhone 3G hardware, will there be anything that prevents me from testing my applications on this iPhone even thou开发者_如何学Pythongh it doesn't have any service?

There is one catch to the iPhone: it needs a valid SIM card (though maybe not current service) in order to activate it after an upgrade or restore.

No. It will be similar to developing on an iPod touch.
