Interesting to note that it also causes problems on the i6 on the GSM which I use. My texting ability was also altered irreversibly about 3 updates ago, I can only send about half my texts with balloons, is that corny or what. The answer may be to get off the GSM network if you can, my answer is to get an android phone which I am going to do, as soon as I can accidentally wreck my iPhone! I will stay with Ting as they are great, but I don't like Apple.
