Hello buddies, I tried first to search instead of opening a dummy post.

My problem is that I am not constantly sticked with my phone, and I am missing the SMS notification, almost every time, when someone calls me it is perfect, very loud and sounds last as long as I pickup or they hang, however, with SMSs only a tiny sound comes, and if I am not giving atention I miss it, my previous phones keep flashing or making sounds until I notice the new SMS, is there a way to keep the N900 giving me alerts until I notice the SMS?

As a bonus, if theres any way to achive that same keep alerting to missed calls, would be awesome.

Thanks in advance.
