So I understand I should be able to use bluetooth in my iPhone 4S to accomplish 3G websurfing on either my MBP or iPad I. I think Verizon charges $20 a month for the pleasure, which is less expensive than paying $25 a month to get 2gb of data on my iPad. Question I -- Does this tethering work well? When I was looking around about tethering, I kept seeing posts/websites discussing jailbreaking. What is jailbreaking? If I jailbreak an iPhone (I understand that this can't be done yet for a 4S), does that mean I get free 3g service? free tethering?
