Need help choosing a good smartphone for AT&T (Help please!)?

I have the centro the the battery life IS OK. If you charge everynight you'll be fine. you can always get it and if its not the right phone for you you can return it within 30 days. If you want a real WORK phone try the tilt. It has a full keyboard but its very business-y. You can get that for about $200. You can also try the pantech duo but it has a very cheapy feel and can break easily. I wish you the best of luck!
