Re: yellow text icon
Check your saved messages (I assume you can save SMS and MMS). Maybe you accidently saved one.
If that is not it, do a hard reset (battery removal, with power on, for at least 30 seconds) and check again.
If still there, highlight the date bar in your messages folders and select mark all read from the menu.
If that doesn't fix it, you could try changing your theme to another of your installed themes, then change back.
There may be other tricks. If the above don't work, see what others say.
Your last resort is to do a clean reinstall of the OS and restore your data from a backup. Or live with it until it clears on its own.
