I already answered about bluetooth. 4G is 4th generation of the celluar wireless signal generally has faster upload speeds and download speeds than 3G depending on the wireless carrier and the location you are in.
wifi is basically a wireless hot spot in one location like a coffee shop or at home with your own wireless router.
