WhistleOut – cool site for comparing cell phone plans

I’m stuck in a contract with Verizon, but if you’re shopping for a new cell phone, I found a cool site called WhistleOut that helps you compare plans for the US, UK, New Zealand, and Australia.  I liked the UI, where you can select the type of phone, how many minutes, data, texts you want, etc.   Even lets you indicate whether throttled data speeds is OK (after a certain baseline amount).
