Honorable mention to Slimshady0 - he was second in order of helping me and verified what MDAIIIUser was telling me.

In this message you will find what my problem was and what I did to get my phone unlocked -

First - The Problem - (keep scrolling down to find the solution)

Here is the scenario:
I bought a Siemens SX66 on eBay.

IMEI 353030000772202

Model# PH20B1
CPU: Intel ® PXA263
ROM Version: 1.20.10 WWE
ROM Date: 10/08/04
Radio Version: 1.02.10
Protocol Version: 1337.38
ExtROM Version: 1.20.115 WWE

I live in Kimberly, Idaho, USA 83341 - Cingular is not available in this area but the SX66 is tagged for the cingular network. There is only EdgeWireless - A Member of the AT&T wireless network, but they have a different SOC (system operator code) and SID (system identification number) than AT&T or Cingular.

Problem - because there is no Cingular in this area, the phone will not work. when I put in my SIM from Edge Wireless the phone displays the SIMlock page with the following Error Message - "Network is locked, Please input unlock code"

I was told that the phone is SOC locked (limited by certain System Operator Codes) instead of SIMlocked I don’t know if this is the case, all I know is the error message that I get.

Now for the solution -

The solution for me is made possible by www.imei-check.com

For this week it is only available to members of MoDaCo

but soon you can go directly to www.imei-check.com and they will be able to help you, or maybe you could contact them now directly through email.

Anyhow, I downloaded their program and followed their instructions with one exception - in instruction #2 they stated
"2. Hold down [CAMERA] and [POWER] button......."

My SX66 doesn't have a camera and so I had to use the Record button (looks like a little audio tape) that I imagine is in the same place (it is on the left hand side with the up and down scroller - there is one button above the scroller and one button bellow the scroller. I used the one above it)

I had to pay their fee (20 Pounds) which was $38.85 USD because of the poor exchange rate ($1 USD = .514897 Pounds Sterling)

But after buying the phone on ebay when it first came out for $700 and not being able to use it for 2 months because of the SIMLock - I felt it was very reasonable.

Make sure you back up all your data before you start the process because when you do this it will erase everything that you previously put in it - It will revert back to its original "Out Of The Box" state.


They say it only takes 5 minutes from the time you submit your IMEI and your file that their program creates and pay for it with PayPal. Well I got
the code in like 10 seconds, but I had an issue with my restore through ActiveSync, it wasn't able to restore everything, but by trying restore 3 more consecutive times I was able to get everything back on the phone with it unlocked. It is so Awesome - I have been waiting to use this phone for 2 months - Thanks to all the people that made this happen. - RED

please feel free to contact me directly if you need help with this - but be patient because it usually takes me a day to reply

I wonder if you tould you share that program with people having the same problem. Which is the name of the program? Thanks.

I would if I could. - The program only generates a binary file that you have to send back to the company and then they auto reply with your unlock code that is encoded in that binary file - if you think you can hack it I would be happy to send it to you - RED

I am desperate!!! Does anybody know how to get a free unlock tool for xda III? It´s impossible that people having xda I or II can unlock their device freely, and people having xda III can´t! Thanks!

Hi RED,

I woould be interested in that binary file, I have been playing with the unlocking program disassembling and looking at the parts of source code which were readable, but didn't have the time to go through a hard reset of my device. Would you be kind enough to send it to me?
My email address is angelos_hw@hotmail.com

Thanks in advance,
Angelos

zouganelis, dou you think you could create a free unlock tool for xda III? thanks.

[zouganelis]

I am not a software cracker or anything, but I can understand how things really work because of my electronic engineering background. I have good experience in assembly coding so I hope I can make some sense from the visible parts of code + the log file. I will keep you guys updated about this.
Cheers

Any news of the unlock software ?

This is a disassembled SimLock.exe file. I think that someone can find how unlock code is calculated from IMEI number, because this exe file is responsible for that.
