texting

How often do you clean your phone of all those old text messages?
If you and your phone are anything like me and mine you have months of old text messages just sitting and consuming phone storage space.
Somehow, and I don't know how, I have a routine of erasing all those old messages once my unread amount reaches 100. You know how it is; you receive a message, but you don't open it up because you clearly can read it the whole message in the preview space. Nevertheless your phone continue to safe and count those unread texts.
Currently I have texts going back to September, and I'm only at 80 unread messages...
