Hi,the question's in the title. Here's the text for Ghost Touch (Weapon Special Ability).
"A ghost touch weapon deals damage normally against incorporeal creatures, regardless of its bonus. An incorporeal creature's 50% reduction in damage from corporeal sources does not apply to attacks made against it with ghost touch weapons. The weapon can be picked up and moved by an incorporeal creature at any time. A manifesting ghost can wield the weapon against corporeal foes. Essentially, a ghost touch weapon counts as both corporeal or incorporeal."
Now it doesn't say "Essentially, a ghost touch weapon counts as both corporeal or incorporeal for the purposes of attacking incorporeal creatures", so can I assume this means it counts as incorporeal for the purpose of attacking normal creatures also, granting it the ability to make touch attacks, as per normal incorporeal attacks?
