no, I can't find the T-mobile official version rom.

I use the unlock 9520, so I don't have the username and password of the t-mobile, than I can't download the T-mobile version rom from the blackberry.com.

Does the vodafone version rom can't load into the unlock T-mobile device?

Here is your Issue. T-Mobile does not Offer a 9520. So they would not have any kind of OS or "ROM" for your 9520. You will need to download an OS that is either DRM or NO DRM depending on your device. Look threw the OS's here and see if you can find one that best suits you. Do you know whether or not your Device is a DRM or NON DRM device??

Sorry Hodges, but you are incorrect. T-Mobile UK has the 9520.

The official latest OS version for the T-Mobile UK 9520 is .436 which can be downloaded here: Blackberry

hz_helios: Where do you live? Also, can you link me to where you are downloading the newer OS version from?

This whole DRM/No DRM thing with OS's these days is stupid if you ask me and screws up a lot of people.

You are absolutely correct John. I was thinking T-Mobile USA. I appologize hz_helios for the incorrect Info and the confusion. I agree as well John it doesn't make sense to me why they had to throw a wrench in the system with this DRM stuff.

I don't know my device is a DRM or NON DRM. Could you tell me how to know that?

I have downloaded the 436 and installed in my phone. but I can't upgrade the 497 or 580 rom.

Could you tell me the difference between the DRM and No DRM. Did my device just can load the No DRM?

Are there any difference between the methods of load DRM rom and No DRM rom ?

Thank you very much.
