The "globe" icon, as pertains to SMS messaging??? A globe icon on your homescreen indicates an unread browser message. I do not know what correlation this has with SMS....
A checkmark simply means the message went through, and a checkmark with a D means the message was delivered.
Sorry, I wasnt thinking their for a minute. the globe appears when I send mms, then it will show a checkmark and finally the delivered part. Could the globe mean it is configuring to send the mms?
