GPush worked great when I first purchased and downloaded it. I write “worked” in the past tense because their servers were apparently not ready for the demand placed on them. After a few hours emails stopped pushing and hasn’t been operable since. Now PushMail is bringing the same functionality… with one major difference… it works!
When you first start the app it asks if you want to use push notifications. Obviously you need to indicate “Yes”.
You then create an account with PushEmail. The user name DOES NOT have to be the same as the one on the email account.
After that you need to go into Gmail’s settings and indicate that you want to both “Forward” emails to the new PushEmail account’s servers (the email address will be indicated after you set up the account) AND “keep the emails in your Gmail inbox. Only after you take this step will the emails begin pushing to your iPhone.
This extra step is a bit of a pain but fortunately it only has to be done once. Moreover, since it is using Gmail’s settings you can also include a Gmail filter so that only SOME emails get pushed. For example, If I want all the emails from my staff pushed to me but none of the other ones I can set it up to do so. If I only want my Gear Diary emails I can do that too. The system works beautifully now, and while at $4.99 it is a bit pricey, for me it was worth it.
