Re: Can i upgrade my gophone at walmart at any time?
You can upgrade your device at any time. There is two different routes you can go - Stay on GoPhone and pay full retail price, or migrate to a post paid plan.
As you said you were interested in buying an iPhone, if you are going to stay on the GoPhone plans, most retailers (such as Wal-Mart) usually charge more for their devices full retail than an AT&T Store or Apple directly. I would highly recommend that if you are going to buy a device full retail you visit a local AT&T store, this way they can adjust your plan and make sure that your device fully works before you leave the store.
You can also migrate your service to a post paid plan to take advange of our great Mobile Share Value plans and AT&T Next which can keep the overall cost of an expensive upfront charge down. To Migrate you will need to visit an AT&T Company store in order to migrate (and a credit check may be required).

Hope this helps!
