Hello. I am going to buy a factory unlocked iPhone 4S very soon and I was wondering which prepaid carrier would be a better choice for me. I have read up on both of them, but I believe that going with Straight Talk would involve me having to carefully use my data. I believe I read somewhere that you can't watch youtube videos or stream any content, so that kind of disappointed me. I live in Miami, so I don't know if Simple Mobile has 3G in my area. What exactly would be the pros and cons of each carrier?
