Ok so I'm currently a VZW customer and own a BlackBerry Storm. I hate the phone and just found out that because I get a 22% discount thru my job off my monthly bill I will be paying just about the same as I am now on VZW. I'm going to switch over and get an iPhone sometime next month. My question is, is there an app that is similar to what BlackBerry messenger is on BlackBerrys? I love my BBM and will hate to leave it when I get rid of my phone so I'm just curious.
