We had some real problems syncing my wife's Comcast email on the Fascinate also. Took it to both Best Buy and Verizon for help with no luck, they were going to replace it, but were out of the screen protectors for it, so we decided to wait to replace it. I took it home that night and realized that my wife had probably 500-1000 emails in her inbox. I created an archive folder in her Comcast inbox and moved all of the existing emails into that folder and then her phone was receiving Comcast email all of a sudden. Don't know if this of any help to you, but if it is great, if not maybe someone else is having similar problems at least.
