Yea, obviously I was asking for the guy who doesn't live in the same country with the same fucked up cellular system as me to chime in and answer a question he doesn't know the answer to.
Not everyone lives in this fucked up country with a fucked up cellular system. It's like asking a question about the metric system and then getting mad because no one can speak feet and inches. Sorry, there's only so many of us that live in the US you know...
What do you gain by buying an unbranded phone? You don't get a reduced plan rate last time I checked and if you bought a phone on contract, the price of the phone + the ETF would equal the price of a new unbranded phone. Seems like one way or another you're getting screwed.
Yes well the only carrier this works on is AT&T. What you gain is improved device selection. I'd like to think of the product portfolio for the US as a fucked up demented one where the "special" US versions are some weird hiccup in the product line or a derivative of an international version.
When HTC launches its products, I can bet you 95% of its focus is on the global market. It then creates a US version of the product or perhaps some US carrier pays them off to launch something early (i.e. EVO vs Desire HD) for them. Either way, you realize that no carrier in the US gets the full lineup. So while in Europe you can use the HTC Desire S, Incredible S, and Sensation on the same carrier, you get the Incredible 2/S on Verizon but the Sensation on T-Mobile.
By using unlocked phones you can stay with the same carrier (in this case AT&T) and use whatever freaking phone you want to. The catch with HTC is that they only release dual band phones, so you need to count on them to bring the phone to Canada or Latin America, or some other country that uses 850/1900. Luckily, there are enough countries and carriers that there is usually a 850/1900 flavor for every phone they have. The same goes for the other manufacturers although they're slowly going tri and quad band for 3G frequencies.
So yeah, I had the option of using a Motorola Milestone or HTC Desire on AT&T. When I got my Milestone you could only get the pitiful Motorola Backflip. It wasn't until much later that the Captivate arrived. Oh, and I got away for a long time using the $15 unlimited data plan. I was paying $30 for unlimited data AND text. What a steal.
Using a GSM network with unlocked phones is how you benefit. Verizon will never let you activate a non Verizon phone even if the networks are compatible. T-Mobile's fucked up AWS band means you have to get an AWS phone, though you can sacrifice 3G like getting a non 850/1900 phone for AT&T and just using it on 2G. But I'm sure sacrificing 3G is a pretty big tradeoff for an unlocked phone, so no one would really want to do that.
