I have a TELUS HTC Hero and a few days ago I was visiting Seattle. While roaming on AT&T my Hero would not do push for my Exchange mail. When I checked the update frequency it was set to "As items arrive" but the field said something like "Sync disabled while roaming". I find it really stupid that this isn't a user setting. Has anyone else found this? The other odd thing was that I couldn't send out mail via Exchange while roaming.
