nokia didn't hold back on features because the carriers told them so. their model worked fine overseas and its how practically every other manufacturer works. they design a phone and if you want it, you sign up on board. It's why Nokia's been knocking it out of the ballpark for years in other countries and can't even enter the US market.
I spoke with the VP of Nokia Research and he heavily criticized the subsidized and branded market of the US. Subsidies are fine in the way many other countries do it, but in the US it's all about carriers signing a deal to have some "exclusive version" of the phone. They wouldn't sell a Nokia N95. It'll have to be branded with not only an AT&T stamp but also an orange/blue box and loaded down with bloatware. I bought a Telus Milestone and while that was SIM locked, the only thing different about it was that it had a Telus movie on it and the homepage was some Telus page. There was no Telus stamp on the hardware. The box itself said Motorola Milestone like it could've come from the UK or Asia. That's the extent of branding that goes on in many other places.
In the US, the carriers are like the gestapo in that they want to control every aspect of the phone. They neuter phones, change the outer shell just so they can differentiate one little bit. Not every manufacturer wants to play ball with that, and that's why the US misses out on a lot of phones. I suspect the carriers fork over a great deal of $$$ trying to get these exclusive phones. I'd rather then spend that money on network improvement, especially in the case of AT&T.
BTW, Motorola is the worst of all manufacturers as it sucks on Verizon's left tit to survive. After the poor reception of the Motorola Milestone due to its locked bootloader, I'm almost confident that everyone ran away from the Milestone 2. Most of those international users jumped on board with HTC and Samsung. Motorola probably gets a huge payment from Verizon to keep the Droid branding going and to keep releasing these phones.
What is this "nokia" you speak of?
