What is the difference in the "Email" and the "Gmail" app on the phone. Wich one should i set up my email with. I use gmail for both of my email accounts. Right now both of my account are showing up under the gmail app, but when i click on email only one shows up. Am i missing something here? How is the best way to set up my email? Also, i do not think my phone is vibrating if i have my email sent straight to a label in my gmail account. Is it supposed to be this way? is there anyway to change it so it will still alert me?
