One of my most-used apps was "Push for GMail", but since IOS 4.2.1 the push notifications have been broken. No response after several days from the vendor, either. So, I checked the reviews of several other apps with GMail push capabilities, looking for one to buy, and it seems like they're all broken. Anyone know if this is fixable, or if it's maybe a GMail, rather than IOS issue? Alternatively, anyone know of a Gmail push app which is currently working?
