I got a ZTE Maven 2. It's free at the AT&T store. You just have to purchase a month of airtime which is $30 or $25 for auto refill.
The screen size is 5"
It doesn't have alot of free space. About 2GB. I need to get a SD card for it. It does have Dolby sound though.
It's a huge upgrade from my ZTE Maven. I ordered a case for it that will be here Monday. I'm using this as my main phone.
You can also get this offer online through their site.
