I just got a iPhone 2 days ago. I have just made the switch from Android and so far I really like my device but I keep having this issue and I notice it more when i have my iPhone connected to my car stereo vis USB. The sound will just all of a sudden stop coming through my speakers in the middle of a song. I recently stopped using my Zune since I just got the iPhone. I have used the Zune for 2 years and have NEVER run into this issue, whether playing it through my car stereo or through ear buds. I also got a new car stereo 2 days ago as well and i noticed that the sound cuts out usually when the iPhone is connected to the stereo. i though that it was probably the brand new stereo or the iPhone cable that was faulty but then today at work while listening to music on my iPhone (with ear buds) the sound cut out again. I had to pause the music and then unpause it again to get the sound to start playing out of the ear buds again. The question I have is, do you think this is a possible software issue that maybe a hard reset (wipe data) would take care of or is this a possible hardware issue in which would require me to get the iphone replaced. Any help would be appreciated. Thanks.
