For those of you out there who might actually be excited about the proposed purchase of T-Mobile USA by AT&T within the next 12 months, here’s some potentially good news for you. It looks like the T-Mobile G2x by LG may have an extra feature under the hood that neither LG or T-Mobile was willing to announce at the device’s official unveiling. According to device information on T-Mobile’s website, the G2x supports not only T-Mobile’s 3G and 4G network, but also AT&T’s. As you can see in the image above, T-Mobile’s AWS/2100 band is listed, but so are the 1900/850 AWS bands that AT&T currently uses for their HSPA+ network. This could be a typo, but there’s speculation that this has everything to do with the purchase plan, and that T-Mobile is simply future-proofing their devices.
