Hi guys, this is my first post here so i will go right to the subject.
I have bought on ebay a BB 8700c from cingular mobile it came unlocked the i am using now with a vodafone card.. It has the 4.1.0.377 Os. I would like to change my os to the latest version the 4.2.
The problem is since i am portuguese i would like to download the multilang version of it, but i cant find it, except the one from at&t. So my question is can i install the version from at&t on my 8700c without expecting any complications?

Thanks in advanced

Yes, all of the software is written by RIM and released by the carriers.
You can put "AT&T" software on a "Vodefone" BlackBerry

Check out the instructions on BlackBerry FAQ - BlackBerryFAQ on how to upgrade and follow them precisely.

Good luck!

Thank you very mutch i will now upgrade my 8700c...
