New Siemens SX 56 ! How to unlock ?

[bmksc]

My device information :
Siemens SX56
ROM : A.30.09 ENG
ROM date : 01/01/04
Radio version : 4.21.00

I've read all the topic here, but nothing can't apply to unlock my Pocket PC. Can anyone help me with this ?

Thanks so much.

you can't unlock it while you have any WM2003 ROM ... you must down grade to PPC2002 ... SER v1.2 is good for that.

So can't have any solutions to unlock it ?
Cause I doesn't want to downgrade it, it's not a good way to unlock.

Hi,
I'm new on this forum and I see that there are very knowledgeable about the at&t siemens sx56. I just purchased one, and I intend to use it with my t-mobile service. It is un-locked with the at&t logo but I would like to sign up for e-mail and internet with t-mobile using this phone. Do I need to update/change the ROM as I've been reading on this forum, and how do I change the ROM to a t-mobile? I would also like to know all he things I need to do to make it run wih T-mobile services. Thanks in advance.

There is no need to change the rom, you can manually enter all the settings for your services once you have them from your service provider or from this forum.

Can you tell me more details ?

thanks, how do I change the settings from At&t to the t-mobile setting. t-mobile will not give me any instructions since the sx56 is for at&t. I would appreciate it if you can provide me the setting or point me in the right direction. Thanks.

First, spend some time reading in this forum and use the search option ... then go to the kitchen and cook 3.17 based ROM ... flash your ROM which will be unlocked by that time ... then cook any other WM2003 ROM to upgrade your xda ... 4.01.16 is very good option
