As long as it's for 8310 no it doesn't matter. But by asking it makes me think you may not quite be ready to take this on. Be sure to read up on what you're about to get yourself into. http://forums.crackberry.com/f3/prop...ocedure-53359/
I have already successfully completed an upgrade to OS 4.5.0.55. However at the time there was only one link for that OS. This one lists two. I would think that it would be unneccessary to list two links to two versions of the same OS if it didn't make a difference. Thats the only reason for my question.
