Open Internet then Menu/Settings delete cache.

 

An easier way is to empty the trash file from your computer. As long as you have your e-mail accts synced, they will also be removed from your phone. I just verified this on G-Mail and my Optimus S

 

I use the free 1-Click Cleaner app to do this. While the name is somewhat misleading, it doesn't really clean all caches in one click, it seems to be an excellent choice for non-rooted Androids and is very thorough in seeking out and removing junk files.

 

Make sure you put your apps on your SD card. Main drawback is some widgets will not work unless they are on your internal memory.

 

You might try History Eraser.

 

iv been getting that memory icon lately too,.good advice, I didnt know trash emails effected it , I try to keep cache clear, and history, there,s some good idea,s on utube , look up optimus s app , it will speed up phone too, there is also one called android booster.

 

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.

 

As soon as I take my phone off the charger for the day I will check that.

 

JUST DOWNLOAD ANDROID ASSISTANT

Its a free app on the market... Really helps you maintain everything on your phone!

 

It also has a few more hidden things in the menu.
