Default Can rooting be used to unlock network lock

Hi, I have xperia x8. I want to change network but the fee charged is ridiculously expensive (almost half the cost of the phone), or maybe I bought the phone too cheap. So anyway I'm looking for cheaper alternatives. The only company I know that can unlock xperia phones is www.fastgsm.com. Anyone knows any other (trusted) one?

THere is a lot of discussions here about rooting the phone. Can we unlock the phone this way? Is the locking thing kept in the file system?

Hi,

No you cannot unlock a network lock by rooting. They are two different things.

A network lock is quite complex, it can be lock in a combination of ways...

1) Mobile country code (locked to a country's mobile network)
2) Mobile network code (locked to a mobile phone provider's network)
3) Mobile station identification number (SIM lock to a specific phone)

Most common is a mobile network code used by AT&T to lock iPhones users to their AT&T network. And mobile station identification number used by Verizon - to lock user of WCDMA/CDMA phones to their network. In this case the SIM card is enclosed in the phone so you don't have access to it.

Rooting an android phone is a different animal altogether. Rooting gives you administrative user level access to the software of the android phone. It is similar to jailbreaking on Apple iDevices.

With administrative user access to your android phone you can...

1) delete applications that have been installed on your phone by your network provider that you don't want to use (usually adware/bloatware/trialware).
2) back up your phone operating software including all the applications that you have installed to your SD card (usually xRecovery or Titanium Backup)
3) install custom ROMs specifically designed to run on your android phone - for example Cyanogen 2.3 Gingerbread ROM for Xperia X8.
4) use applications that require root access, for example tethering applications to create wifi hotspot using your phone's 3G network so you can surf the internet with your laptop.

cheers

yeah I thought there was a way to tweak the setting via some system files to get around the network/sim lock mechanism. The reason I asked was because I saw a file called simlock.ta in x8 firmware 2.1 rus. SO I thought if somehow we could flash a modified one we could change how the lock behaves. Well maybe not.

Thanks Gabeyong. I tried following up on the links you gave me. They all point to SE Tool. From what I gather this is a paid tool which you need to buy credit to access the server for unlocking code. Unfortunately all the download links both from mega upload and fileserve are dead links.
Anyway, I have gone ahead and paid for similar tool from FastGSM. Basically it flashed something to the phone. So yes it was a system file or some sort that was replace/removed or modified.

Hi,

I thought there was a mod to get 25 credits for free?
I think it was a baseband modification to accept all networks.
Similar to iPhone unlock. Anyway...

cheers
