Hi guys,
I spent a lot of time trying to do this and would like to share my SUCCESSFUL efforts with you all!
First let me clarify some of the terminology. Sprint and other carriers program their hardware EPROM to their network specs and lock access to it. This lock is called the MSL code!!! [Master Software Lock?? :-p]. You would need this code if you want to make any changes to it.
Electronically Programmable Non Volatile (ie a fixed value chip)ROM which is also called NV Rom (NV in short) is where the carrier customization are stored and read from when the phone boots up. The unlock process changes the carrier data to be read from a SIM card instead of from programmed NV. Also note that CDMA or GSM SIMs are actually called RUIMs in the tech world (<--Wiki this). Something I learnt the hard way...
Second, this is not rom flashing (i.e putting another OS on your phone's SSD card and updating the boot records). You will be programming the phone and if you mess up mommy wouldn't be able to help you :). There would be noway to unbrick your phone so check your USB cable (most common culprit) virus scanners running on your PC etc etc.. before you try this.
Please thank Vinod Nayak at Rimweb for putting this all together for us. I am in Tokyo and have followed these guides to successfully unlock my Sprint LS990 to work on AU by KDDI (albeit only with 3G speed). So if you are still reading get a cup of coffee and head on to the sites below and read on. Please note you may need to register on their forum to see the screen caps (recommended).
You need the MSL code to reprogram your phone. Follow this guide to obtain it first and keep handy.

There were other guides found on XDA that will find your phone's MSL code. Once you have this go to the next step below..

Let me know if it worked for you!! Merry Christmas and a Happy new year to you all!!
