Hi, I am working on an iPhone app and I am trying to make something that has to do with line-circle collision detection. I am using the slope of the line and checking if the coordinates of a circle suffice the equation y = mx + b. But, with the current origin (0,0) at the top left it is a pain to get the slope. Any way I can convert the coordinates so the origin is in the center of the screen?

Hi,
Once I connect my iPhone to my computer, is there anyway I can look at the directory structure on the phone?
Would it work like a USB device for example and let me copy files without using iTunes but just drag and drop through the Finder on a Mac?
Thanks,
Tee
