So now that iPhone OS 3.0 supports Push notifications I am wondering - will it cost me to receive a push notification while roaming? I have data roaming turned off when I am in Canada, but I still use my iPhone with Beejive messenger in Wifi hotspots. And Beejive will now push me an IM message while I am away, and I know that this happens over the cellular network although it's not technically a text message or regular data usage. Would a push count as data? If so how much? A few kb? Would my iPhone just reject push notifications while roaming if "data roaming" is turned off, or will it charge me?
