I’m not entirely sure what you’re trying to say here.
I don’t really know about mobile submission methods myself.
I would hope they’d work fine, but if they’re not I dunno what to tell you aside from… well, don’t use them. Mobile tends to be crappy.
But either way we don’t USE Tumblr’s submission form anymore, we have our own and you just have to click the submit button on our tumblr to take you there.
