Will you be updating ActiveSync

I don't like the app very much and would much rather use Sparkle app which works with ActiveSync. However, when I try to use ActiveSync to set it up, I get the message that a very old version of ActiveSync is being used and please ask the administrator to update ActiveSync on the server. Even with the default iPhone email client, mails are not very smooth. Sometimes deleted emails reappear and appear as unread.
