Ok so I just put the new 4.5 os on my blackberry and it had aim but for some reason was saying that it couldn't be used on this handheld or something like that. So I decided to do the thing that I did when I first got my blackberry. To delete the aim that my blackberry already had and install it again from blackberry.com/aim. Because the first time that worked great, but now that I did it again it says it cant install because it doesn't work on this phone. And I'm just like stuck trying to find a place I could download it from. Does anyone know what I should do??
