wat. I just checked, I have Location Services set to 'Never' on Dropbox and it uploads files fine.

It was about two years ago. I removed the app, never looked back. But recently came across a news that Dropbox got hacked and all passwords were captured and leaked. At the same time I received an email from them, not mentioning that (as far as I remember) but what they mentioned they will delete my account if I don't login in the next x weeks. It seems Dropbox had its peak, and it's going down-hill from there -except they do an IPO or find a someone to sell (maybe they already do just that).
