I've tried to configure an iPhone 3GS with OS4 with the new public beta... I've got the hole calendar to get synced, but I get only 3 mails.. Not the last 3 mails, not the first 3 mails, custom 3 mails from the inbox of groupwise.

Sending mails works fine, but new mails are not synced... I see always only 3 mails in the mailbox of the ipone.

Any ideas ?
