I agree with Meister. Phone photos are not acceptable to ME.

The technical quality of the phone photos are still crap, regardless if they sell.
What do you mean by technical qualities? Grain? Dynamic range? What?
There are millions of DSLR photos, Film photos that also have crap technical qualities. There has been a trend for high grain, high contrast B&W photos over the past several years, crap technical qualities? What about high contrast, over exposed colour photos, crap technically? Maybe, but it's the image that counts, what is captured, what emotion it evokes. Lomo, Film, P&S, digital, leica, Zeiss, all have different qualities, strengths and weaknesses. The photographer uses the best tool for the purpose, the tool that will get the result the photographer wants.
Do Terry Richardson et al need a Leica S2 or Hassleblad to get the P&S snapshot aesthetic they became famous for? Oh no, Richardson famously used a crappy P&S to get this look which print fashion media went crazy for. Crap quality, crap camera, but unquestionably pro (Terry Richardson's moral code aside).
This snobbery over mobile photography has cropped up several times on this site. Pros, real big time pros do use mobile phones for pro work that is published by news sites and magazines the world over.
