Any other 3GS users having issues w/emails using iOS 4.0?

No, not that issue but i did just get an email and it said "this message contains no data". I couldn't delete it and it kept showing that I had a new mail. After 3 tries the email finally "showed up".

 

I am only having issues with my gmail accounts right now. One is imap and the other is on exchange. My yahoo account is working great! The gmail's not so much.

 

same here...gmail not downloading new mail

 

Interesting, I had the same issue no more than an hour ago. Let's try to narrow down the issue. In my case the scenario was:

- Using MobileMe
- Organized by thread set to On

I am not sure how I solved the problem but I think I turned the "email thread" off. Sorry for not being more specific but at the time I saw this problem I was actually testing the "Organized by thread" function and I was turning the option on/off.

 

No problems for me....I have Gmail, yahoo and comcast. I love the improvements!

 

It seems to be a temporary Google issue. Enable IMAP until it's sorted is the only answer at the moment. Here's another (recent) macrumors thread on it.

 

Indeed, many have been suffering the same issues. I actually started a thread about this yesterday when my Google Sync packed its bags!
