I finally received my phones today! So far I am very excited and impressed. I got the phones online with VZW but I skipped through the G-mail set-up. Should I set up the G-mail or do something different? Will it affect other Google stuff on the phone if I do something else? The screen that has all the icons on it like facebook, u-tube, corporate calendar, etc. how much of this stuff that is preloaded should I use because it's good or do something else because it's garbage? Thanks in advance for your help.
