Do these apps allow you to transfer any font you like to the iPad or do they come with some preinstalled fonts?
After some research I have found a method to manually add any font you want to the iPad. I am, however, unsure if one is allowed to post something here from another blog.
Update: I've tried this manual method, and it pretty much worked like a charm! I have added a few new fonts to my iPad using it.
The preferable way would be to copy the procedure and paste it here.
