Re: Hiding iphone 3g when bluetooth is switched on
Hi! The bluetooth feature on the iPhone is currently limited by Apple to the headset profile and will only function with bluetooth headsets. File transfers, object push (which are the BT profiles exploited by bluejacking) are not activated.
It is not visible to other devices so you dont have to worry. :-)

Just on home screen Settings > General > Bluetooth > Switch on Bluetooth, & also switch on bluetooth of another devise with you pairing with iphone 3Gs. I phone wil discover this device. Use passkey & get paired.
You can't send and receive files with the iPhone's bluetooth. Version 3 of their firmware will supposedly provide this functionality, but only on the iPhone 3G. (2G models don't have the necessary hardware)
As for the hands-free car setup, that should work just fine. It's a matter of pairing the two devices together.
This problem doesn''t deal anything with your iPhone 3G. This could be a headset issue. I have tried connecting different Bluetooth headset to my iPhone 3G and I experienced the same problem using the Bluetooth headset of my friend.
To isolate this, please try the steps below:
- Try to disconnect/reconnect the headset via Bluetooth.
- Decrease the volume of your headset while making a call.
- Try to connect the headset using different profile. (for example, you connected your hadset using the headset profile, next try to connect the headset using handsfree profile to see if you will get the same problem)..
- Try using different Bluetooth headset to see if there's a problem only with your phone or with the headset
I actually have both products, and I was able to get my bluetooth to work with 2 phones. All you have to do is first pair your phone with the H721. Then in the phones functions, turn off the bluetooth so it is no longer in discovery or connected...but do not turn off the bluetooth itself, just in the phones settings. Then go to the bluetooth settings in the iphone. you should see the H721 in discovery but not connected. Before connecting it you must put the H721 into discovery mode as well. Hold all three buttons down for 19 sec. it will go solid blue. then push connect on your iphone. onces connected, go to the original phone and turn the setting back on for bluetooth connection. both are now connected. Only one may apear to be connected, but both are. test it with another phone. call each number and you will see that you can now answer both calls with one device. If the iphone is connected and phone 1 rings...the H721 disconnects temporarily from the iphone and connects to the other device to answer it. Hope this helps. Cause thats how I got mine to work.
the iphone 3g bluetooth is at present for headsets/handsfree devices only and cannot link/pair with anything else (phones/pc etc) it has been deliberately crippled to force file transfer etc to be done exclusively through itunes
