Day 3. One Thing You Can’t Live Without- My iPhone. I know that is such an average answer but seriously. Everything I use is in there. Camera- to document everything in picture form.Notepad- to document everything in written form.Kindle app- because I love the read.Contacts- so I can always reach my loved ones.GPS- so I know where the hell I am and where I’m going.Expedia- so I can book my trips on the fly.iTunes- so my movies, music, etc are always RIGHT THERE. It’s life on a phone. Stupid Apple.
