*UPDATE* Adding AT&T to the list below.
With BlackBerry 10 launching today, the first thing every BlackBerry user wants to do is get their hands on the new devices. Unfortunately, most users only buy their devices from carriers so carrier release information is extremely important.
So far in the US, Verizon and Sprint have put up their BlackBerry 10 "More Info" pages. Verizon allows users to sign up to be kept in the loop with everything relating to BlackBerry 10. Hopefully we'll see AT&T and T-Mobile jump on the BlackBerry 10 info bandwagon in the next few days.
