Profimail is a symbian OS application capable of using SSL (6600 does not have inherent SSL support for POP email). The software
AFAIK is NOT FREE. You can get it from:
http://www.lonelycatgames.com/mobile...profimail.html
Just download the ZIP file (Trial version) from the website, unzip it and transfer it to your phone using IR/BT. Open the file by going to the INBOX and run it.Profimail installs and then you can set it up for using GMAIL. POP setup instructions are available on the GMAIL help site.
Hope this helps
