A reader Denzel asks..

I am thinking about finally upgrading to a better phone and service. I am deciding to buy an iPhone 4s or 5 on ebay. I want to know how can I use straight talk or net 10, but I am little confused how to get the better end of it. I just don’t know how to set up everything without any problems. I just need to upgrade my phone and wonder if I can just keep my iphone to current carrier Metropcs or just switch.

Hi Denzel,
Sure. I think I could help you out. Can you tell me a little about what phone you have now, how much you are paying per month, have you set a budget for your phone and monthly charges, and are there any special features of the iPhone that are important to you?
