I don't see that the "trash" issue was resolved. I am up to android version of 2.3.3 and still there is no way to empty the trash on my pop3 email (I don't use gmail and I use the android email to connect to Comcast.)
It is just extremely strange that this topic is all over the internet yet there is still no way to empty trash on my phone.........a basic function of email.
Rather than getting another program, how about the writers of android fix the problem. It makes no since that some can do it and some can't.
