Unread messages/missed calls icons.

[TechnoPhobic]

Hi guys,

I have recently upgraded the android system on my phone (xperia arc S) to 4.0.3. When I get new messages or missed calls there is no icon on the screen to tell me so other than in the top display bar. Someone I know who has the same phone but is using the older version of android has an icon come up on their front screen. This is before unlocking the phone and simply says '1 new message' or '1 missed call' etc with the picture for message/missed call next to it.

Is there any way of getting this on the new android system?

Thanks.
