it all depends on what you want to use it for. probably best advice is to figure out what you want to use it for and how much (do you want a mobile internet browser / smaartphone / apps, or do you want a proper phone, do you use long distance, do you use a lot of text messages, is daytime calling important, how much per month can you afford, etc) and then take that info to the phone companies and see what they can do for you.
