When I see someone write something as completely moronic as "There is no reason to pair the iPhone with the computer otherwise.", I feel compelled to comment just to set the record straight. If proper Bluetooth functionality is not something that you require, then fine. However, don't go making ridiculous sweeping statements assuming that no-one else would ever want this ability.
Perhaps you are one of the people who will also continue to use Apple's Map app instead of Google's app. Because there really is no reason to know the correct location of places, now is there? (Just in case you didn't get it, I was being sarcastic 😉 )
By the way, I did choose a different device for my personal phone. I bought a Samsung Galaxy S3 for myself which is an absolutely fantastic phone - easily the best phone I have ever owned (and believe me, i've owned a fair few). And yes, it does support all of the aforementioned Bluetooth features.
Unfortunately, I was given the iPhone5 by my company, and have had no end of problems with it 😟. Hence why I seem to spend a lot of time on these support forums.
