What are the pros and cons of each phone? Keep price in mind... I am trying to get on a plan with one of these phones but I don't want to end up paying outrageous amounts unless it's actually worth it! So tell me about these phones if you can, and speak in English so I can understand. In other words, don't try to use all the fancy mobile lingo assuming I know exactly what you are talking about (like 6907 MGQ or whatever)
