I highly doubt three carriers will be releasing the same device in the same month. They got this article from infosync and that page doesn't really establish any sort of release date. I could put together a page with four photos of the same phone with the exact same specs (T-Mobile's version WILL have 3G and they're frequency is 1700/2100 MHz not 1800/1900 MHz like this chart states) and then plug in any date I wanted, it doesn't make it true. Also, T-Mobile will have UMA capability. This is a generic chart with no credible information besides the hard specs of the phone which we all know.
