I have an iphone and it looks like I am getting another one for work. Now I need an app which will allow me to use GPS navigation as well as hands free. I happened to find a device from Apple which allows the hands free and now I will just need to download the GPS app. I bought and downloaded the app. Now am I able to put this on my Iphone as well as my work iphone? If so, how do I do it?
If you bought the app straight from your phone you'll have to sync that phone to your computer using iTunes. Once you've done that the app should be on iTunes and you can then sync the other phone to the same computer. You can go through and check things that you don't want synced on to your second phone too. If you don't want music taking a bunch of space up you can choose not to have that put on when you sync it. That SHOULD work, if not, I'm out of ideas.
If both phones are synced using the same iTunes user account and to the same computer, the app should end up on both phones. You just have to sync the one with the app, and then the other.
