I frequently get text messages from people where the Exclamation mark is replaced by a Question Mark on the incoming text messages. So some messages like like: Great to see you??? When it should say.... Great to see you!!! Has anyone else seen this or know what causes it? It seems to happen only sometimes and it does not seem to matter what type of phone they are texting from. At first I thought it was just the sender, but noticed it's happening with other contacts too. I'm on the iPhone 4 with iOS 4.2.
