I am going to get either an iPhone 4S or 5 here in about two hours. I currently have a iPhone 4, which is cracked badly on the front and back. I was eligible for an upgrade last March with Verizon, who unfortunately doesn't offer unlimited data anymore. I am extremely interested in jailbreaking it as soon as I get it. If I jailbreak it and tether internet to my iPad will it be using the data that I have on my plan? Also would you guys recommend me jailbreak it or not? Also what site would you recommend me go to to jailbreak it? Thanks in advance.
