GUIDE:
As this is a hack, this process will be very similar to the process of flashing a dead Nokia.
1. Search for Device RM-819 on your favourite "firmware download application".
2. Launch Nokia "Product Support Tool For Store 5.0".
3. Select "No Connection" on PST drop down menu.
4. Go File -> Open product -> Select "RM-819".
5. Go Programming -> Recovery.
6. Your recently downloaded firmware should appear on the screen. If not, make sure you have correctly set the "Product" folder and click update list.
7. Make sure that you have removed your screen lock password. (Helps PST to switch phone between modes on restarting, if required).
8. Select your firmware and click start.
9. This should result in an error message.
10. Just follow the error message, Unplug the USB cable->Power down the device(In some cases, it will restart when you remove the cable)->While holding the "Volume up" button, reinsert the cable->Click "Retry".
11. This should start the flashing process, which should result in success.
To Answer the questions:
1. FW to download is "Nokia 800 RM-819 Country Variant Puerto Rico PR Black V1 (059N5J2)". Not sure if you should be using this on cyan.
2. FW Version is 1600.2483.8107.11501
3. Qualcomm did not create a new SOC especially for Nokia, with one frequency gone missing. All the chips are uniform, it just reduces the production cost.
4. Nokia could have implemented a software lock on the frequencies to curb the inter-continent phone sales.
5. Difference between the two: RM-801 is the 900Mhz version of Lumia 800, for Europe, Africa and Asia. And RM-819 is the 850Mhz version of Lumia 800, for Americas.
6.If you are in Europe, Africa, or Asia; Please use RM-801. RM-819 will introduce limitations to your device.
Please backup your data and do it at your own risk, blah blah blah. This will disable high speed data on 900, and enable it on 850.
Feel free to comment and post your results. Good luck!

Test Results:
-All the existing functionality has been retained.
-After 3 discharges, battery capacity still at 1437mAh.
-The Battery capacity shown, may vary with the battery temperature, perfectly normal.
-Big improvement on Cellular data. Network B/W on Rogers 3G jumped from 3-4Mbps to 11-12Mbps. This means High speed is working.
Doubts:
According to some speculations by "fshqbizfs", it still does not enable 850. (Thank you).
After looking into the Nokia RM-801 Schematics, I found out that, even though the SoC can support 850, Nokia RF circuit is limited to not support 850 Mhz. I believe that my "H" symbol and higher speed, was a mere coincidence. I guess 850 will never work, unless we swap the RF circuit out.
In the end, this becomes a really long way of installing firmware from a different Device. O Well!
