iphone 4 won't find any device

Same problem for me also. Just bought my iphone 4 this month and try to use the bluetooth feature. I try to pair it with my wife's iphone 4, switching ON also the bluetooth of my Windows 7 PC & Nokia phone but it only keeps on searching and cannot find any device.My PC and Nokia phone can detect my iphone 4 but when i paired it, error occured. IS IT NORMAL? I heard that iphone 4 bluetooth can only be used for pairing headsets / hands free devices. IS IT TRUE? I haven't tried yet on pairing some bluetooth headset.

You can't use bluetooth to pair to another phone for things like filesharing.

(my husband's iPhone) Having same problem, including iPod touch. What's the point to have bluetooth on iPhone 4 if you cannot use it as the other mobiles, mainly when you need it so much to connect it whit car to be able use it as handsfree. Specially when in those days many cars has bluetooth build in to make it hassle free - turn on, pair and go. No such problem with HTC incredible. If is there any solution please let me know!!!

Bluetooth on the iPhone will connect with cars unless you own a car that uses the rSAP protocol.

kurtmherz13,

I don't think that it was either NORMAL or TRUE.

I bought two iphone 4 from Verizon yesterday(Jul 6, 2011) with 2 same bluetooth hands frees.

I also have a built in car hands free with my Toyota Rav4.

So I started pairing bluetooth devices. One phone(#1) has no problem at all. (Even once it was paired after phone #2)

The other phone(#2) could succeed to pair once to hands free #1, very slowly.

Then, it did not recognize either hands free # 2 or toyota bluetooth.

I removed hands free #1 from the phone #2, and turn bluetooth switch off then on, then restarted phone #2 - no recognizing device

I put phone #2 on dash board and restarted again - no recognizing device

I put phone #2 on cup holder, then restarted again - no recognizing device

I left it hoping that finding a device just takes time - Spent 20 minutes in the car, engine running and the phone being charged. Still looking for a device.

Again, Phone # 1 does not have any problem at all with all 3 hands free system.

I also recognized that phone #2's connectivity is not as smooth as phone #1's. It was much slower and even dropped signals several times in an hour I tried to buy some apps while I had a break.

At that time I put phone #2 on the table, so it is not because of "death grip."

Both phone #1 and phone #2 are using iOS 4.2.6, so it cannot be solved by "software update."

I strongly suspect some hardware problem called 'lemon.'

People who spent their time and money updating software and changing bluetooth devices including hands-free should be compensated.

I think that the only solution is replace to a new iphone which is not a lemon.

Hi guys,

might be not interesting anymore, but I found an answer for my problem (connecting samsung bluetooth headset to my iPhone4S) here:

I hope it is still helpful for someone. (;

Same problem with iPhone 4s. I does not see my Jabra head set that works fine with other phones. Apple, we know you do not like to admit flaws, but seems like there are enough of us here that you should get it fixed.

THANK YOU ... I've paired one car and I think 4 headsets to my iPhone 4 w/ NO problem, then got a new headset and it wouldn't pair. As others noted, it just seemed stuck in "searching" mode. I turned the iPhone off and back on, still no results. Watched your video and started the process with the headset off and WITH BLUETOOTH TURNED OFF on the iPhone (never had to do that before), put headset in pairing mode, then turned bluetooth on. As before, the device would show up on the list as "not paired," but this time when I touched the line on the device that said "not paired," it found and connected. Weird. As I've said before, I have never had to start w/ bluetooth turned off on the iPhone, and instructions always say to make sure that bluetooth is turned on .... anyway. THANKS! --- MAR 5 2012

Glad to hear! (: Sometimes nuances matter...

Have a good day!

I have tried this and several other nuances and my iPhone 4S does not see my headset or my wife's headset in pairing mode. Both headsets work fine on other phones.

I have just got the new iphone 4s 16gb and downloaded the software update which has new bug detection on it an d my bluetooth just continues to search devices and the other phone finds iphone but says connection failed. check that other device is within range and bluetooth is on!!! Very frustrating as i use bluetooth alot , please help i almost didn't get an iphone because you always hear about these bugs for this and that for apple products its bad enough you don't get a proper manual to even to tell you how to open it up to put a sim in and then i realise it is a micro sim which i was not sent, 3 days on my phone is now operating and now this!!!! heeelllp from an i phone newcomer!!!

Try to restart your iphone and then try the bluetooth again...
