Text Message - 1 Unread SMS

Been having this problem on my smartphone. On screen it says, 'text message - 1 unread'. But all sms has been read. Luckily I found this website, Freeware for Pocket PC which has the tool to fix the problem. Best of all, there are hundreds of free software available for smartphones / pocket pc out there. Salute to the people who come out with this brilliant software creation.
