My Pre is reporting that a tipster with a webOS emulator has found that the Pre will use IMAP IDLE. This means that users on GMail will have near instantaneous reception of new emails. Because it’s getting pushed to the phone from the GMail servers.
Pre users are going to love that. At the moment, the only phone to support GMail push is the G1 (and soon the HTC Magic or any other Android device). Palm’s relationship with Google is proving to be extremely awesome for Pre users.
