Today will forever be remembered as the day threaded messaging came to Nokia's Symbian platform. An app called ThreadSMS, in the soon-to-be-shuttered Ovi Store, will display your messages in a threaded format. This is quite revolutionary and magical. This is the feature people have been waiting for.
Unfortunately, other platforms have had this feature for almost half a decade. This is why Symbian is going away. Goodbye, and don't come back.
