Ever since I got this phone, it has been nothing but problems. Here's a list of everything that is wrong with it:

-The screen goes blank and I have to remove the battery to get it to start again
-The pages freeze up
-I won't get messages all day, and then when I restart it, all my messages suddenly appear
-My phone will work everywhere but my own house, and it never used to. Says it has lots of signal, but i can't send or receive messages or calls
-It's sooooooooooooo slow!
-Web is even slower
-Can't get on the web, even when it says I'm connected

This is the majority of the problems. Anybody know if this is caused by something, or how I can fix it?
