Isn't that convenient. With only weeks left to go before the official Windows Phone 8 launch event, what's likely a version of the HTC Windows Phone 8X with North American LTE support has stopped by the FCC for approval. The PM23300 variant we see here (the international 8X is the PM23200) supports both the needed 700MHz LTE band for its eventual appearance at AT&T as well as AWS for wider AT&T coverage and the big three Canadian carriers. All are good signs that HTC is just about ready, although T-Mobile and Verizon subscribers might not want to get overly excited just yet -- there's no AWS 3G, CDMA or Verizon-ready 700MHz LTE to be found on this 8X, which shows that any US launch will still demand multiple editions. The others won't be far behind in the FCC race with that November release window already locked in.
