Friday is update day, and Apple might just drop the new iTunes, new MacOS and chances are they will drop iOS 4.2 public release today. iOS 4.2 GM was released to developers a few days ago, and no one reported any major bugs or issues. The only known issue is that you have to run the latest iTunes ( which is currently in beta – and might be released today ) in order to activate your iPhone.
We already talked about the upcoming update of Cydia, but we also want to remind you to make sure you have your SHSH blobs saved. Anyone with blobs for iOS 4.1 or earlier should be able to get an untethered 4.2 jailbreak.
