Finally I found a way to add multiple Gmail accounts and/or G Apps account to push service

I was asking around here about how to use Google Apps email push service on Android. However, I found no good answers and I end up adding my G App account to the Email app which can't handle push services from Google Apps servers.

Anyway, here is a way to add several Gmail accounts(or app accounts) to your main Gmail app. You can read about it at: Multiple Google accounts on Android Gmail ? Sanuja Senanayake

Hope it helps Google Apps accounts holders
