1. You can add Calendar Entries / Contacts and SMS people via PC Suite!
Many people do not realise that the old school PC suite if you still have it DOES work with the Nokia N9! Here is a screenshot of the N9 connected to the PC suite via the USB cable. This is the best way for business users of the N9 to type SMS messages from their computer. So if you can get a hold of PC suite, this is your best bet. I've also screen captured the version I am using in case others do not work.
2. Transferring music - Nokia Link for N9
The only software specifically put out by Nokia for connecting the Nokia N9 to your PC or MAC is called Nokia Link. This program, however, only allows you to transfer music and photos. However, the software does not run on Windows XP.
3. Ovi Suite does not work with N9
It has been confirmed that the Nokia Suite is currently not supporting the new Nokia N9. Yesterday Nokia Suite was rebranded from Ovi Suite (and before that PC suite) but nothing was said about the N9. Below is a screenshot of the "thanks for coming" screen what I got when I tried to connect the N9 via Ovi Suite.
One of the easiest ways to connect your computer with the N9 is just plug in the USB cable to the phone and computer and select "Use for Mass Storage". On your "My Computer" you will see your Nokia N9 show up as an icon or under "Phone Browser". Note that some applications on your N9 will not run whilst your phone is connected to the computer in this mode. Also good to know is that your phone battery will also recharge whilst your phone is connected in this mode.
5. You can't install apps via PC Suite
PC Suite had the best chance of doing this but when I tried to drag an application to the phone, it looked at me funny and said:
6. You can't install apps via Nokia Store website
Usually an option appears in Nokia Store that allows you to download the application using your computer and then remotely send it to your phone via bluetooth/cable. You can't do that with the Nokia N9. It will only give you the option of sending an sms to your phone to continue downloading and then installing the app there.
7. Use bluetooth
Your computer will be able to transfer files to your N9 and the other way around just using bluetooth if you have that on your computer. Just pair your computer with your N9 and away you go. This will be slower than using the USB cable.
