I have the annoying Exclamation Mark on the SMS icon. I know it has something to do with a failed SMS sending. But when I push the icon it opens the SMS app as nothing happened... The most stupid thing is that it does not show me which is the failed SMS!!! I have thousands of SMS in my iPhone that I do not intend to simply erase them all... Is there a way to find the failed SMS and so get rid of the Exclamation Mark on the SMS icon? Thank you in advance!!!
