There are lots of reports about Nokia "Curse of Silence" SMS bug these days, the commonly recommended way is to use F-Secure to repair. F-Secure does can fix this,however,dont you think the price is a bit high?

Here I got an app to recommend.MCleaner is a SMS and call firewall. It as natively solve the bug. It can not only defend,but also can repair! Say,if you installed MCleaner,you wont get into the trouble;or if you have had the problem,once install MCleaner,the SMS function will recover automatically. What's more, it only needs $11.99,much cheaper than F-Secure!

There is a 15-day trial period,you can go to MCleaner--blocking incoming calls and sms on s60|UIQ|Linux|iPhone|windows mobile to download and try it!
