I am planning to get a iphone and when I do go ahead and sign the store Im getting it from is going to throw in a jawbone with my iphone. My question is I already got bluetooth in my car which I would use whenever driving and it automatically syncs when i get in. I was wondering would I also be able to have the jawbone synced too at the same time or would I have to unpair one to use the other and pair it back when using the other. I was planning to use the jawbone for the store and so on and the car bluetooth for when driving.
