help...what does it mean by...

ok i have a SE s500i and im going to get it unlocked by professionals since no one in my area can do it.
im going to use this site:
S500i Sony-Ericsson Unlock Codes for Mobile Phones and Cell Phones

but i have 3 quick questions:

1)what does it mean by "Locked to provider"?
does it want me to put my cell phone PROVIDER, or the provider that it was originally made for (so that i cant use it on my provider, which is AT&T)
if that made sense...

2)Im located in the US, does the fact that this site is "located" in the UK make a difference?

3)has anyone used this site before?

help a new guy out :]
thank a bunch.

It means what service provider the phone was originally bought for example:AT&T, Rogers, Sprint, etc.

o..well the problem is, i got it off the internet so i have no idea.
is there a way to find out?

If you want to unlock it by patch(not permanent), we can help you if you connect with SeTool2Lite 1.11 and post here an identify log(without IMEI).

o really?
how long will it be unlocked?

you mean this?

It will be unlocked until you reflash it. You have EROM CID53, so, in order to unlock it you must follow this video tutorial: ANYCID patching - Top Sony Forums

o thank you!

AH i need help...

Extract the AnyCID.ZIP. In your phone folder, you should find a zip file which contains executor.b !
As an example you can find the following zip file in w580 directory R8BE001_CXC1123362_GENERIC_LA ! This is the ByPass Package for w580 R8BE001 Firwmare.
Here RBBE001 indicates the main firmware version for which the executor.b works. So you better make sure you have a main firmware for which executor.b is available. If there is no ByPass package for your firmware, then you need to read instructions given later at the end.

whats the bypass package and firmware thing?
are they the same thing?
where do i get it? (i couldnt find it on google)
I kno i have a:
R8BE001_CXC1123326_GENERIC_LY
from looking at the file, but im so confused.

ANY help would be MUCH appreciated. thank you!

You'll find "executor.b" into the folder "S500", if you extract the archive named "R8BE001_CXC1123326_GENERIC_LY"(3kb).Fortunate ly, you have R8BE001, otherwise you had to flash the phone first. Also, if you extract the archive named "db2020", you'll get "customize_upgade.xml" and "executor.jar". These three files are the bypass package. As for the firmware, look here: SonyEricsson Hardware and Firmware Definitions! - Top Sony Forums

ok, so if i download a S500i firmware, then i can continue on with the steps right?

I really appreciate your help hyperion17. this whole thing unlocking problem has caused me stress for like a week trying to get all this situated.
