Try the MailDroid app, I think it better than the stock email & GMail app that comes preloaded on the phone plus it pushes the email with no noticeable batter drain.
hey .. i did and it literally worked for half an hour.. i have deleted and reinstalled and still doent work.. evebn tho i didnt wanna do this i prolly should have to save frustration - > fwd non gmail email to gmal and just use the gmail app
