So I'm kind of confused here.... The PAYG customers won't be shut down 100% right? It's just their data that might not function... right? Iphone 2g/3g users can still use PAYG service, but if they don't switch to a PYP, their data won't be the same? This is confusing. Anyways, I'm using a Iphone 2g, and here on campus I get free wifi so I don't even use a data plan. If updating to OS 3.0, will that be okay?
