I've had this phone for a couple of years and its great. However I noticed it has become slightly laggy when browsing menus and navigating around. Is there a reason for this?

I deleted all my inbox texts all my sent text and drafts but it is still kind of laggy. I'm using a 1gb card with it which has about 900mb free. The phone has about 45mb free on it. I only have a few pictures and music on it.

The other issue I have is when I delete someone number and contact for good but when I receive a text or call from them it knows the name of the person even though I deleted them off my contacts..how does it know? The thing is if I have deleted their number from my contact and want to add them again to it, it wont let me either. As the option is not available anymore on previously deleted contacts. Usually I just "save number" from their text but that option is no longer there on deleted contacts. How do I sort this out?
