A little info about the iSync plugin for the N97

Question

Several 3rd party developers have confirmed that something is broken in the way the N97 communicates via the iSync plugin. Nokia has changed, incorrectly implemented, or out right made something wrong and a firmware upgrade is DRASTICALLY needed or a plugin will NEVER work. The problem started with Nokia and ends with Nokia. They need to fix the problem with the N97. The developers feel that unless Nokia fixes this problem there will never be a plugin for the N97. It is as simple as that.
This is all the info that I have at the moment. For the time being the only way to sync your data is:
1. Prepare all of your data the way you want on your phone and then us Ovi. This can be a problem too as Ovi is not that great and is not very stable.
2. You can use Memotoo (www.memotoo.com) to sync your data via SyncML. I have used tried it and it works okay. Better than Ovi for sure but it costs.
3. You can use The Missing Sync by Mark Space (www.markspace.com - currently testing). It does not use the same way to sync via iSync plugins. The Missing Sync sends a plugin to your phone instead. The syncing is very stable and works flawlessly. The only drawback is that the phone plugin is not exactly designed for the N97 and it requires that the N97 needs to be reboot sometimes to sync. Other than this, the operation is flawless and it appears that Mark Space will be able to fix this one problem faster than Nokia will be able to fix their phone.
Hope this helps......

Yes, once you have MfE, you can sync N97 to Google Calendar and Gmail Contact list. The Mac's iCal app can add the Google Calendar. For Address Book, there are two choices: Access Gmail Contact via LDAP, or do proper synchronization in iSync style (see http://lifehacker.com/393855/enable-google-contact-sync-without-an-iphoneipod-touch).
MfE is not "installed" by default in the N97, but it is actually there. I need to credit someone on this forum for mentioning it, but I'm afraid I forgot who. The steps are basically thus:
Basically go to the Menu -> App folder, look for Settings Wizard "Sett. wiz.". Try to setup an email account from there. Don't use your gmail account though (it seems like MfE tries to be smart when it recognizes some email domains and pre-selects some settings for you, but we need to be able to access some options to set on our own). Don't worry about this account, you can always delete it once MfE is configured. At some point of the setup, you will be asked what kind of server. Choose Mail for Exchange. This will trigger Mail for Exchange to be installed.
Subsequently you will see your MfE folder populated with Mail for Exchange and other stuffs. Get into it and configure your Gmail. Some settings to note:
Exchange server: m.google.com
Secure connection: Yes
Use default port: Yes
Username: Your gmail username (just the name, no need the @gmail.com part)
Password: For the gmail account
Domain: gmail.com (I believe blank is also ok, but mine is current set as such)
Make sure that synchronization is set for Contacts and Calendar only. Tasks must be disabled (it used to be because Google Calendar did not support Tasks, but even they do support Tasks now, it still breaks MfE). Email must be disabled.
Done.
I did have further trouble though. The sync keeps hanging and then eventually "Invalid Password" error (yah right, after sync halfway they realize my password is wrong... no, something else is mucked up). I eventually deleted my phone data, and re-sync it from Google again, and everything was fine.
Once you've got your phone data on Google, you can search Google for other tips on pulling the data into Mac.
Hope you have fun getting this to work.
