The HTC One is officially on sale at AT&T and Sprint as of today. Both carriers and their resellers are offering the aluminum beauty in its silver appearance at $200 on contract for a 32GB model, with AT&T still holding the US exclusive on a $300 64GB version. Those who are waiting for different colours or radios will have to wait a little while longer, however. The T-Mobile edition won’t officially land until the 24th, and a black 32GB model is still “weeks” away from landing at AT&T and Sprint. Provided you’re not the exception to the rule, though, you’re cleared to buy what’s arguably the first US-bound flagship of the year.
