I found a blackberry I can buy for 40 dollars, used but in good condition on ebay.

I don't mind buying one used, but I want to know if they are worth it or not. Can anyone give me a good reason to buy it, or tell me why I shouldn't?

Any opinion is great, thanks.

Also, I'd like to mention I do need a cellphone because the back of mine has fallen off, I've had it for a couple of years, my cellphone is pretty much "mooning" everyone and showing off it's lithium battery.

I also have verizon
