Could you please give me the code you used to do that? And any other text formatting codes (aside from those in the toolbar) you may know of? I tried to use superscripts the other day with [sup]1[/sup] and it did nothing, despite having been listed as a BBcode on some website I looked up....
As I said above, I will hunt around the 'net and see if I can find anything to help you out.
I understand your frustration with the thread getting hijacked, and I apologize as I'm to blame for that. I recently started a thread about difficulty taking pictures with my iPhone and it was completely and savagely derailed, including by someone claiming to be a manager here... Nap.. Na-something, I can't remember his name at this point. But it's not important.
I've seen this once before in a forum or blog somewhere. But it was only after a new screen was installed. I don't recall the solution, however, I think it has something to do with the screen's connection to the phone's internal parts.
