Motorola RAZR V3m

I have a Razr v3m (Verizon) and like everyone knows, it's often sluggish, i.e. sometimes it takes a second or two to perform a UI action, just opening messages, or if I hit the camera button by mistake, it takes a couple seconds for the cancel button to take effect, etc.

So my question is: is there any way to speed this up? Any way at all (short of using a different phone)? I'm willing to add RAM, hack it, whatever. I'm not all that cell phone-savvy so I'm sorry if those are stupid suggestions. I just like the Razr's design but don't understand why it's so slow. My friend has a much cheaper, seemingly crappier, Verizon phone and the UI is perfectly snappy.
