To me, it's not a surprise. If they're launching on T-mobile USA, they must have EDGE, because T-mo's 3G coverage is still rather limited; even if they were going for AT&T, EDGE would still be likely. That means, in practice, a GSM-capable radio. What wasn't known was whether initial software would support it, and if not, whether devices shipped with voiceless software would be upgradeable yo voice in the future.
