I have a friend in a distant state to whom I iMessage URLs once in a while, pretty straightforward stuff, from news sites or youtube or the like. She gets the iMessages on her iPhone 4s, but she is unable to open the URLs. Perhaps there is a setting on her iPhone that is not set or...mis-set, but I haven't a clue as to what to advise her to do. Is some additional software package needed that she can download? I have no problem with these URLs on my iPhone 4s. Here is a shortened version of a URL I sent her: http://tinyurl.com/73lxq8w I can open that tiny URL or the full version without a problem. She can't open either. Advice, please...thanks!
