Hi, Thanks to all that replied to my iPhone bird song app question. I still haven't figured out how to use this new iPhone as a phone (but that's OK, because other than calling my wife, I make about 5 calls a month, and I've never texted....so i'm glad the calls/texting are unlimited on my plan.....just kidding...I don't care about that....I got this phone for one reason only -- birding.). Still not sure what an app is................. Tim Antanaitis Middletown, CT
