Blackberry update

Ya. I was told I can put pdf files on my blackberry. what I was not told is that you have to buy the application to do so. 1 year subscription is $49.99. not much use on a 2 year contract. the unlimited access is 79.99. less than buying it for 2 years, but what is the use in buying it if i am only going to have the phone for 2 years. hummm. must think about this further. maybe even camp out at verizon and have them explain a little about the blackberry after the 2 years is up.
