First, sorry for the newbie question. I've followed this forum for a long time but just lurking. I bought an Iphone 4 over the weekend and had a question about whether it is best to use the built in mail feature or the google gmail app. I use gmail for all mail. I've noticed the mail app doesn't seem to work in 'push' mode for gmail. The emails only come through when I open the app. But then the gmail app doesn't popup any alerts or noise when I get a new email like I thought it would. Which app do you other gmail users use?
