[I-Hate-Hulse]

I'm in the midst of evaluating options to sync my work's Exchange server (mail, contacts, calendar) with a new iPhone or Blackberry.

For the iPhone, I was wondering if anyone could share their experiences of syncing through Outlook Web Access specifically. Any glitches or annoying things I should know about? I have this working on an iPod touch at home, and messages seem to disappear after 2 days. I have to think this is a setting somewhere - it's not in "Settings - Mail" though.

For BlackBerry - BIS only does Mail, not calendar or contacts. For a variety of reasons, I can't use my existing BES service. So again, I need something to sync all three items with Exchange at work via OWA. I'm looking at AstraSync - has anyone used this? Experiences? Alternatively if you know of any good BES alternatives that work via OWA, please let me know! I'm not looking to host BES Express so that option is out. I'm not with corporate IT so any solution has to be via OWA - I can't install anything on the corporate side.
