i use it for messaging (usually text not iMessage as I don't know very many people that use iMessage.) but even my texting is not something I do with a lot of people. Skype (which notifiers seems problematic), AIM (yeah it just sorta running in the background.) Tidal (my Lossless streaming music), phone calls and that's about it. are there other things I might consider taking advantage of? if so, what. maybe I shouldn't though, as I still got no clue how to do the editing for iOS. There are lots of things I don't know about the stock apps, like I am presuming by listening to Blind Bargons that iBooks is for books on iOS. Health? no clue but I h assume it has something to do with fitness bands? Game center (but are those even games w that that would work with VO?) um. what else. ITunes I know is for transferring content from PC a to iPhone and back... the reminders and calendar are self explanatory as well as the clock. but what are things like passport? what's the difference between camra and photo's? I know with camra you can take photo's and the photo's app is what you use to view the photo's once you have taken them? Is that it? Vidios, is that for if you take vidios with your phone that's where they'd be? Notes, never used that. Stocks are something I wouldn't use. I know how weather works and like that. Newsstand? what is this? the app store I know is where yuou go to get free or paid apps for your iOS device. and iTunes store is where you purchase music and movies if you are going to view them on your phone (which I wouldn't probably do).
