Outlook/iPhone syncing with Exchange AND .PST

Question

I'm having trouble achieving a desireable configuration after my company upgraded to an Exchange server.  Here's my set up:  I use my personal laptop for both business and personal use (Win XP + Outlook 2007).  I also have an iPhone 4S.  In addition to my company email, I have several POP3 accounts on different servers that are not related to my main job.
Before the Exchange migration, I had Outlook setup to poll all of the POP3 accounts (including the old company email) leaving a copy on the servers for a few days.  I also had my iPhone set up with the same email accounts so that I received email on both places.  My Outlook calendar, containning both personal and business events synced perfectly to my iPhone.  Lastly, I used a separate Contacts folder (~300, mostly personal) to hold only those contacts that I wanted to sync to the iPhone (my full contact list in Outlook is 1500+ and not wanted on the phone).  This setup worked well for years.
Now after my company upgraded to an Exchange server, I am having trouble replicating this setup.  It appears that Outlook now uses a different storage file (.OST) and is using "cached mode" as set up my our IT department.  All of my old contacts, calendars and email folders are still stored in the original .PST file that now appears under a separate "Personal Folders" heirarchy in Outloook.  The other POP3 email accounts are still using the .pst file and Exchange is using the new .ost ("Mailbox") file.  Ok, so far.  I can live with this.  However, after I synced my iPhone (using iTunes) all of my contacts and calendar events were deleted from the phone.  Not Good.
For email, I set up a Exchange email account on the iPhone and the company email is coming through OK, as are the previous POP3 accounts.  But the contact list and calendar is not working as expected.  I want the contact and calendar data from my .PST file to sync to my iPhone - NOT the Exchange folders.  The reason is that I do not want my personal contacts stored somewhere on my company's Exchange server.  The same can be said of my personal calendar items.  When I added the Exchange account to the iPhone, I turned off all but the "Mail" option.  (Contacts, Calendar and Reminders are off for this account.)
It appears that in order to sync these via iTunes, I have to copy/move them into the .OST contact/calendar folders, which I don't want to do.  The iTunes sync options for my phone will not allow me to choose anything from the .PST file. 
How can I get the contact and calendar info from my PST file to sync to my phone?

roknjohn,
We need to skip the whole Exchange discussion and ost and pst files. This is not needed to troubleshoot the problem.
iTunes will sync with your Outlook default account. Do not confuse the default account with default data file (pst or ost if it comes to Exchange server).
Your solution would be to make the email account where you store your contacts and calendars as the default one.
This can be done in Outlook, Tools, Account Settings.
Make sure you are in the Accounts tab not the Data Files tab.
If you start changing default data files for your different accounts it will get messy. Besides Exchange will not allow you to do easily.
Please post your results.
