Hi - I just got the iphone 4 and I can't discover other phones or my imac/macbook. To me this seems like the thing is broken but I spoke to my provider and they said its normal and all I can use the bluetooth for is headsets and things like that. Can someone please explain in dummy terms what it can and can't do bluetooth wise (can i send or receive files, control Logic on my imac etc). When I try to search for info its all explained in a language Im not familiar with. So please anyone....... explain it to the noob It would be very much appreciated!! ps. Other devices (phones - macs) can see my iphone but not the other way round - I semi paired with it via the imac but when you actually hit connect on the iphone it just cuts out. Thanks for your time people!!!
