Either T-Mobile is already requesting manufacturers produce their phones to future-proof them for the AT&T acquisition or LG realizes the benefits of economies of scale. While I’d predict the latter, either way it seems the latest hot handset from T-Mobile will be equipped not only with T-Mobile 4G but also with AT&T 4G.
While the future-proofing is a nice theory it is unlikely. Chances are that LG saw themselves launching this device in various markets and preferred to mass produce it with a variety of radios rather than engineer, earn FCC validation, and jump through all the hoops of two almost identical devices with different radios.
It’s a nice touch by LG but if anyone wants to toss their conspiracy theories in the ring… the comments are the place to do so.
