I have had issues with bluetooth discoverability. It seems that the iphone is only discoverable in the bluetooth menu. A real pain when trying to autopair with the car stereo - I don't want to have to go into the BT menu everytime.
I also checked the discoverability with my nokia - no problems when the iphone was in the BT menu but no luck when it was on any other menu.
It is a 3g with version3.1.2
any advice???
I am having the same problem with a GTX Bluetooth Visor Speaker Phone Handsfree Kit. I have it paired fine but I have to manually go into the Iphone BT settings and tap on the paired item. It is a pain each time to do this. I found something online that works temporarily. Here is the post:
Ok, the trick is this: (you'll need a landline phone or another cellphone to get it to work) get your phone to pair your device, make sure your iPhone it's registered to the deck, then leave your iPhone on the bluetooth screen where it says "discoverable"... then you'll need to call your cell phone or send a text message to it... THIS TAKES IT OFF OF THE BLUETOOTH SCREEN BUT LEAVES YOUR PHONE IN THE DISCOVERABLE STATE!!!
this works for me, but only for a short time. Any ideas or other suggestions would be welcome. BTW I also have a 3G with 3.1.2 software and jailbroken.
