other than trying to touch the exact location?
I think so, depending on what you mean by the above. Press and hold in roughly the right spot, and a magnifying glass will pop up to let you slide the cursor into exactly the right spot.
There is a bookmark for the iPhone User Guide in Mobile Safari.
If you already found the magnifying glass, no, there's no other method. Send feedback to Apple here, as they are not checking these groups for problems:
