When I delete my emails from my Sprint HTC EVO phone they automatically delete from the Comcast server. Why won't they auto delete from iPad? Every time I look at email on iPad I've to manually delete hundreds in order to remove. Can't it sync via wi-fi just like my cell? If I read email from a computer via Comcast website, whenever I delete from their server it auto syncs deleted emails to cell so I don't understand why it can't do the same for iPad2? Is there a feature I need to turn on? Thanks!
