Hello everyone,
I've been following several forums about the lack of bluetooth on the iphone 4s, and quite frankly, I am very surprised that such an issue has not been resolved by Apple. I am in no way an expert on the iphone - I just bought two iphone 4s' a couple of months ago, for my girlfriend and I, and had a great time with it (taking pictures, recording videos, making calls, listening to music.. etc) but, we didn't know that we wouldn't be able to transfer the files to either phone via bluetooth. Instead, we had to go home and sync the phones so we can "then" transfer the files.
As KiltedKim mentioned before, on her October 27th, 2011 post, "The iPhone does NOT support bluetooth file transfer. It never has."; and then again on her November 18, 2011 post "OK. Let's try one more time. The iPhone has never supported bluetooth file transfer. You cannot pair one iPhone with another."
So the answer is pretty basic - bluetooth file transfer and pairing of one iphone with another iphone is not available and is not supported.
In my situation, and like many other users out there, I cannot simply throw away the iphone for the lack of bluetooth and call it a day - I have to deal with it and hope that one day Apple will fix this issue and make it available for everyone... 🙂
