Does anyone know much about this? (the new rules, that is - not dumping Pepsi on phones...) I've got an iPhone 5 on Sprint that I've had over two years, so I assume that means it can be unlocked since I have completed the two year agreement I signed.

1) Can I take it to another carrier, perhaps installing my AT&T SIM card into it. Are there other restrictions that Sprint won't remove that would prevent this?

2) Are there any other carriers (or MVNOs) that I can use this phone with that might be a better deal than the $100/mo. I'm spending with Sprint? I don't do a lot of calling or texting, but I do want to continue with unlimited data.

Thanks!
