Sorry if there are other topics on this, but I am having a hard time finding what I am looking for and I have multiple questions. First, I want to install the newest os leaked for my tour. I know that I should wipe my blackberry first, is it ok if I just do it through the phone without using a third party app? And secondly, I'm using a mac with mac desktop manager and I can't figure out how to install the file I downloaded. Any help or tutorials for a mac would be greatly appreciated. Thank you all for your input!
