...how do I go about using it for guitar playing on road trips? My wife and I recently changed from Sprint to Verizon because of better coverage. (We started RVing and couldn't get a signal in a lot of places with Sprint.) So I've got this brand new iPhone that's as big as a brick , and I'm this technologically challenged doofus that was drug kicking and screaming into the 21st century. I've read comments more than once on TDPRI about using one's smart phone for playing (electric?) guitar in certain settings (workplace break rooms, hotel rooms, etc.), but I've got no clue how to do that. On our RV camping trips, this could come in handy, if I knew how to do it. So, I thought I'd ask. I have no doubt any number of my fellow TDPRIers will be able to enlighten me.
