I got an AT&T Tilt2 yesterday. Its a great phone, except for one thing. The bluetooth REALLY SUCKS! It will not pair with the Uconnect in my truck or a Motorola headset. I google the problem and sure enough, they changed the BT chipset and there are all sorts of problems. Supposedly, HTC is working on a fix. Only time will tell.
Since Im not willing to give up the bluetooth built in to my truck, Im going to put the SIM back in my 8525 until they come out with the fix. Since I only paid $99 for the Tilt2, its not worth returning.
