Can you tell if an iPhone is locked or not from the UA string? Because I'd expect that locked iPhones are exactly the customer you want most: has money and signs long term contracts (whereas an unlocked or jailbroken product might indicate that they'll do extra work to save money -- exactly the customer you don't usually want).

Well.. you could but you would need the IP address also.

You just need to check if the request is coming from a T-Mobile IP, or any other GSM carrier in the USA (http://en.wikipedia.org/wiki/List_of_United_States_wireless_...).

This wouldn't work outside the USA (unless you want to research the carriers) and most people would be connected to wifi.

So, this wouldn't really work. It would be much easier with a BlackBerry as they transmit the vendorID (a type of carrierID) in the UA. You could easily check this with the IP.
