Unfortunately it's normal here in the US.
Yeah it is normal in the US for carriers to act like they're the BOSS. If AT&T is in Asia or Europe, they will be the manufacturer's B***H and have to provide service based on the device not the other way around like in here.
When 3G (UMTS) phones came out back in 2003, Hutchinson 3 network started to provide the 3G services including VIDEO CALL (which until NOW still not yet here in the US), Broadband speed data, and many others. Other network, started to follow.
In here, however, since the CARRIERS are the BOSS, they DICTATED which device gets sold in their store hence they can just deny devices that's way ahead in their time. Instead, they take their own sweet time (read: AT&T nationwide 3G coverage, and even worse is that myth called T-Mobile UMTS Network) and not provide customers with the latest technology available in the market.
Worse still, since US did not use the same network as the rest of the world, it is useless even to get cutting edge devices (read: Europe/Asia 3G phones)
Also, the problem is locked phones. Since the carriers are the boss here, mainly due to obscure network frequency meaning the phones that they offer are only available through them, these carriers are able to lock the phones with their ugly firmwares (read: VZW ugly red firmware, AT&T ugly orange, Magenta for T-Mobile, or Yellow for the dying Sprint). With the lock, it gives the carriers an enormous opportunity to lock down these people to not use other carriers. For example, in many South East Asia countries (where I'm from originally), people can buy subsidized phones but UNLOCKED!!! meaning they can use these phones with other carriers. Contributing to this, is the fact that there are a lot of mobile phone stores around to sell unlocked phones (just like you've seen in Chinatown except they're everywhere)
Now, there is iPhone, where it kinds of defy these norms. iPhone has no ugly menus and this sent shockwave throughout the industry. It boggles their mind that for a locked phones with 2 years commitment, iPhone gets to dictate what software gets into their phone. Little did these people know that numerous carriers have sold unlocked phones with a subsidized pricing.
Until the manufacturers are able to leverage themselves against these US carriers, and until the time people here stop buying FREE LOCKED PHONES with 2 YEARS commitment, the day where carriers offering subsidized unlocked phones are still a long long way.
