Has anyone had issues with their Hotmail or Yahoo accounts on the Captivate? I'm getting a lag on receiving emails from these two email accounts (on and off wifi), getting connection errors and even having my emails disappear completely from my phone's inbox only to reappear later. I did call AT&T and Samsung. Not a known issue according to Samsung. I will be exchanging my unit today and hope that this is a defective unit. Starting to regret ditching my Blackberry device for this phone.
