Problem deleting mail from iPhone

I am having some problems deleting e-mail from my iPhone. When I check my status via …servlet/traveler it says the server is available but I get the following message:

Apple-iPhone: Online and the following changes are pending synchronization: mail:delete .

I can find anything in the trouble shooting section in Domino and Notes Information center and I come up with a blank when I search the troublshooting section on the IBM website.

Subject: More Information

I also have a problem that my trash folder disappears periodically on the iPhone and it requires an uninstal and re-install to clear the problem.
