I per-ordered a 32 GB Wi-Fi iPad; should I give up my grandfathered unlimited iPhone data plan so I can enable tethering to the iPad? In looking at my AT&T plan history, I sometimes go over 1 GB/month data, but have never come clost to hitting 2 GB/month. Since this is my first iPad, I'm not sure how I will use it, but I am guessing it will be mostly at home or at work, where I have wi-fi. If I am without wi-fi, I can tether to my iPhone, although I hear this can be a bit inconvenient and not a seamless process. Or, do I just return the 32GB Wi-Fi model, wait it out and spend the extra cash to get one with LTE...Just trying to keep costs down and not keep things simple.
