MooCow Guitarist on iPhone can turn your iphone into a brick. I purchased the Guitarist a while back since I was intrigued with the idea of playing the guitar on an iPhone. Well initially it worked fine, but after a few upgrades of iPhone and the Guitarist software, it became highly unreliable. In my case it simply freezes the iPhone and after a few minutes it causes the iPhone to reboot. Sometimes it does start, but the sound is muted, and there is nothing you can do to un-mute it. I sent a couple of e-mails to the MooCow support, but never heard back from them. So if you want to get a guitar app for your iPhone, think twice before you waste your money on Guitarist.
