Sony Erricsson P1i Email and Google Apps Email

Just a short update to this.

After successfully setting up my P1i to use my Google 'Apps for your domain' email I have discovered that the messages (new or replies) sent from my P1i are correctly included in the threading of my email conversations. I know this shouldn't come as a surprise but it is worth noting as email sent from my Nokia (E61) where never properly included in treaded conversations.
