Is there a way to delete emails on Yahoo on my iPhone without deleting them in my Yahoo account itself? My concern is that unless I delete emails on my iPhone, the memory will quickly fill up -- but I don't want to delete them from my Yahoo email as a whole (i.e., I want them still to be there when I use Yahoo mail on my computer via the Web interface). Or am I basing this question on a misconception as to whether the emails actually are downloaded onto my iPhone in the first place when I access them using the Mail program on the phone -- could it be that I am viewing them online (as with a browser) but not actually downloading them? In that case, there would be no need to delete them for reasons of iPhone memory-space conservation.
