I own an iPhone4 and have an MKX that is waiting to be shipped that I'm hoping to have next week. I am getting anxious in the true sense of the word about this combo of iphone and Lincoln. I have a Blue Ant two way speaker device that I have been using in my 04 FX. I think I will hold on to it for when (and I say when and not IF based on everything I've been reading) it fails. Pity. As Ford owners, we need to speak loudly with our displeasure and use the tools at our disposal to voice our discontent. Surveys such as JD Power hold an incredible amount of weight and should be used to get Ford's attention if they are not listening to their consumers. I hope mine is fine but if not, I will be using that and every tool at my disposal to get Ford's attention so they hasten a fix for these problems.
