In Feb I asked a question about data connection. I have a question about the response I received from Twerppoet: "You can also chose to leave the Cellular data turned off except when you need it, if you don't mind missing push notifications for email and such when you don't have Wifi." if I turn the cellular data off, will I still receive e-mails that I missed when the cellular data was off or when I don't have WIFI, when I turn it on or have WIFI?
