Me and my mum, both got new phones recently. She got a blackberry curve and I got the iPhone 4. I brought a ringtone of iTunes and use it, and I tried sending it to my mum; using Bluetooth but it failed. Both were turned on, and visible; we were able to connect; but not send. On the blackberry it said to enter a 4 digit numeric code to receive from my iPhone. But neither of us know the code, both of us haven't added and codes or changed any. I was wondering if u guys could help me, are they set with a standard code when u buy it? If so what is it; or if u know where to find it out like on my phone or the book it came with, where? Any help would be great, useful and appreciated.
