We've just received an image from a trusted source that suggests T-Mobile will be encouraging sales reps to push accessories when it launches the Nokia Lumia 710 in the coming days. Of course, none of this comes as a surprise — carriers almost always encourage high-margin accessory bundles with new phone purchases by their subscribers — but this would be the most official confirmation yet that the Lumia 710 is coming to T-Mobile after it announced a New York event next week and let a T-Mobile-branded unit pick up FCC approval. Whether there will be any other Nokia models bundled in with this impending announcement remains to be seen, but we imagine there will be a few folks disappointed if the higher-end Lumia 800 isn't also part of the deal (unlikely at this point).
