You even know the use of data sense? As far as I can work out its a very useful app from Nokia, something I can't live without. Helps me keep track of my data and is at par with the data by my service provider.
Just set the data plan in settings, it'll work out to your current settings. Or advance the date by a month. Don't whine about something you can't use.
Looking at your posts I'd like to quote this, "A thousand monkeys with a thousand typewriters won't be able to recreate Shakespeare's work in a thousand year".
