Can my unlocked Wallaby work with the Cingular GSM network? - Upgrading, Modifying and Unlocking

Hi, I have a Siemens SX56, unlocked with the tools I found here. However, I can not use my Cingular SIM chip, only a T-Mobile (or ATT) one.
Is there any way that I can do something to get my device to work on the Cingular GSM network?
Your help is greatly appreciated.
Thanks

UNLOCKING AUDIOVOX 6600 series PH20A2

Hello,
Anybody can help me please? I bought Verizon Audiovox 6600 from the us and I can not use because it is locked. Please jelp me to unlock the phone,Thank you[/i]
Ive heard there are issues with the Audivox unlocking. I would apreciate some help with that as well. I am getting one from a friend soon. Hes coming to England.
The 6600 is a CDMA phone. I take it your home country has CDMA as oppossed to GSM? Sorry for the basic question but there is no use unlocking it unless you have access to CDMA. The 6600 is not GSM capable.
New Zealand has CDMA, the UK does not.
From what I heard you are able to use the phone for voice only, but not data because the US does data in a different way than Asian CDMA operators. I could be wrong though regarding how the 6600 does data

Will a Cingular BA PH20B work on Verizon's network?

I have searched and searched to find the answer but the forum is large.
I wish to change from Cingular to Verizon as a celluar network. I would like to know if I can go to Veriozon with the SIM (Cingular SIM.. not sure if this makes any difference as I am new to screwing around with my PDA) unlocked or if I need to do something else before I go into a Verizon store and purchase a SIM from them.
Cingular has very little coverage where I am and I really like my BA. I do not want to change to a different phone at this point. What are my options?
It won't work man
Ok... quick breakdown.... Cingular is a GSM network, so is T-Mobile and Various Others. GSM uses sim cards. Verison on the other hand, as well as sprint is a CDMA network and do not use sim cards. There is no device interpolerity between CDMA networks and GSM. So u can't take ur device with u from cingular to verizon, but u could move to t-mobile.
Thank you. I figured something like that since I never saw a reference to Verizon on here.

[bneed some help!!

Hey guys i was wondering if anyone knew how or if it was even possible to use my unlocked htc 8525 on sprint network (CDMA).
Nope, won't work. The 8525 is a gsm/wcdma phone. And I don't think that sprint uses sim cards.

I tought that since Mighty Rom is running on it... it was fullly unlocked... but it doesnt seems to work..
Any help will be appreciated!

You need to get your phone sim unlocked to allow it to work on a different network. Telus can provide it or there are aftermarket ones you can use. Olinex has a sim unlocking service. You can find info on the first post of his HardSpl sticky in the rom section.
Once you have it sim unlocked it will work on Rogers but you will not get any 3g coverage as that phone has the wrong frequencies for the Rogers network.
.... 3g + with telus either
Hey InRBigness
thanks for your quick reply.
This phone isnt getting the 3g+ from telus either... I bought it before they launched the 3g+ network. So I guess its not a big difference right ?
thanks for your help and point of view about this
regards,
