Can someone tell me which one is better for third year? Iphone isn't an option since I need to be on verizon. What are the advantages of each? Are there any programs I will need that won't work for blackberry? Where can I get a list of programs I will need for 3rd year so I can figure out if they are compatible with the blackberry and treo? Also, if someone could just give me general advice on which is better for 3rd year and the long run I'd appreciate. I need to figure this out within the next few days. Thanks!!
