problems with pop mail fetching and application update after 2.1 firmware

Just curious if anyone is still having problems with pop mail fetching after the 2.1 update. I still have long stretches of time where no e-mail is received, and then when I manually fetch mail, I get the spinning wheel and connecting until I exit mail. Sometimes I can get mail after just closing mail, and other times, I have to do a soft reset.

Also, my application update still is not working. I had to remove the application from the iPhone before it would install, and then that was only after a sync with my macbook pro, and wouldn't do it directly on iPhone.

Thanks in advance for any potential solutions to these issues.
