Just ahead of T-Mobile's event in New York City, we've noticed that the carrier has already listed the BlackBerry Z10 on its website. The smartphone is priced at $100 over two years, though the UnCarrier is also offering the BB Z10 for $532 up front. Notably, the handset's listing says it supports 4G LTE -- and we imagine we'll hear a good deal more about T-Mobile's network plans when the event kicks off in just a bit.Filed under:
