Hello Lacy, you could change device name, but please make sure aircraft firmware is 1.9.6, and you need use ISO mobile device (it cannot be changed on android device recently)
Please refer to this screenshot:
Lacy, just borrow a friends iPad or any other ISO device. Load the app, change your name, delete app, return device to your friend. Don't forget to say thanks to him/her.
I couldn't honestly tell you if it'll work on the Ipod touch. Install the DJI GO APP and find out. If your asking if it'll work before you decide to buy an Ipod Touch, someone else will have to answer that before you buy. If your borrowing one, just download the app and see if it'll work.
