9360 Update Question

[earlsweatshirt]

I bought a used blackberry curve 9360 for T MOBILE, but once I bought it, I unlocked it and placed my AT&T Sim Card in it. So now I am trying to see which update I should use or does it not matter?

It would be helpful if anyone can point me to the latest OFFICIAL release for this blackberry.. Because i dont know if I update i will lose my unlock or something like that.. Thanks for any help

once unlocked it will never "relock"
You can use the new 7.1.0.258 update found in teh Leaked/Beta OS section of the forum.
