Had the Treo300 over a month now. Love the always on (when it stays on) data connection. Set up PCS mail right away, notification worked, and retrieve it with Eudora. Peachy right? About five days ago, I stopped getting notifications. I've tested everyday for the last five days - no notificaition. Tested SMS (Treo300sms) - it works beautifully. I changed the notification settings from direct to phone to email to myphone#@messaging.sprintpcs.com (I think it's the same gateway) - still no luck. I'm getting ready to be on hold for two hours with Sprint CS - thought I'd post first. Anybody having similar problem or comments, please post. Thanks for any help.
