I want a new phone, i have at&t for service. i was on there website today looking at phones and reviews that?

people wrote on phones, most people complained about the battery life of the phones, i have had my phone for the last 4 half yrs and my battery life is fine and it is a Nokia, I was also thinking about getting a pda phone as well. i would just like to know what kind of phones you have and if you like them and if they are everything you expected and also are all the pda phone packages the same as the package you have to get for the iphone.
