I bought the iBolt XPro, for Samsung, the day I got my phone. I bought it from the Verizon store and it is packaged for Verizon. It was fine for a while, but I began having issues with it. I would dock and plug in the USB and the phone would go to car mode and immediately back out. It would not play music and other sounds through the USB/Aux combo cable. I reported the problem to iBolt and they quickly responded, telling me there was a two week period where the products shipped with defective cables. This has since been remedied and they are UPS-ing me a replacement cable. Quick customer service and acknowledgement of the issue. If anyone is having a similar issue, email them and let them know.
