Does Exchange 2007 need an SSL cert for Mobile phone email sync

On Exchange 2003 Mobile devices would connect without an ssl cert but on Exchange 2010 we had to purchase an SSL cert for the Mobile phones to sync with users email. Does anyone know if thats necessary for Exchange 2007

Yes it is for autodiscovery.

you can use a Free trusted public certificate authority to get the certificate. http://startssl.com

From my experience, it is necessary for both Activesync and for Outlook Anywhere (formerly RPC over HTTPS).  It will need to be a SAN/UCC certificate with both internal and external hostnames.  We use Go Daddy's 5 domain cert for around $79/year.  Make sure you have control over the email account listed in WHOIS when ordering a cert.  They will send the approval request there.  Hope this helps!
