Okay, there is one serious issue:
http://www.aximsite.com/boards/showthread.php?t=69128
Nevertheless, to set up Gmail, I did the following (just did it again after the ROM update):
Firstly, configure Gmail
1. Go to
http://gmail.google.com/
2. Sign in
3. Go to settings
4. Go to the tap "Forwarding and POP"
5.a Tick "Enable POP only for mail that arrives from now on"
5.b Well I am not sure, whether it is important, but then I also enabled "When messages are accessed with POP archive Gmail's copy"
6. Sign out from Gmail
Then configure the PDA:
7. Start - Programs - Messaging
8. Click on "Accounts"
9. Click on "New Accounts"
10. Enter your email address (e.g.
torsten.pda@gmail.com) (Skip the auto configuration by clicking on "Next" - Sorry forgot this first)
11. Enter user information
11.a Your name: Enter your name (e.g. Torsten)
11.b User name: Enter your email-address again (e.g.
torsten.pda@gmail.com)
11.c Password: ******* (e.g. 1234567890 - this is not my password

)
11.d Tick the option "Save password", if you want.
11.e Click on "Next"
12. Enter account information
12.a Account type: POP3
12.b Name: Name the account (e.g. Gmail_PDA)
12.c Click on "Next"
13. Enter Server information
13.a Incoming mail: pop.gmail.com
13.b Outgoing mail: smtp.gmail.com
13.c Enter "Options"
13.d I did not do anythig unter "Options (1/3)"; Connection says "The Internet"
13.e Click on "Next"
13.f Tick "Require SSL connection"
13.g Tick "Outgoing mail requires authentication
13.h I selected "Get full copy of messages"
13.i Click on "Finish"
This should work now. If you send yourself an email to the Gmail account that you want to access via POP3 from your Axim, then you should be able to download it.
14. Put your Axim into the cradle (Activesync should open)
15. Go to "Messaging"
16. Select the new POP3-Account
16.a Click on "Accounts"
16.b Click on the new POP3-Account (e.g. Gmail)
17. Connect Axim with Gmail
17.a Click on "Accounts"
17.b Click on "Connect"
17.c Monitor the messages from the Axim
18. Read your test email!
Unfortunately, you have to tell Gmail from time to time again, to forward only new emails from now on via POP3... this is a bit annoying... You realize this, when your PDA claims, that there would be something wrong with the set up... Then it is your turn to remind Gmail to forward only new mails.
I hope, I did not miss any important step.
