I currently have AT&T "unlimited" data and will be getting the iPad 3. My main concern is what I should do when I don't have access to wifi. My 4S is not jailbroken (nor do I care to jailbreak it), so the only tether option I have is to dump my current plan and go with the tethered data plan. If I do this, will I be tied to the new contract for another two years? I really hope not because as soon as the iPhone goes LTE, I will be dumping AT&T and going to a competitor on general principle. Another wrench in this problem is if the Ipad 3 does come LTE ready, should I just get the month by month data plan offered since it will be faster than my current HSPA+? Also, does anyone know of a substantial difference between AT&T or Verizon LTE, other than coverage area?
