Apple just (finally) dropped iOS 4.2 which brings all the goodies we talked about in the past, like AirPrint, AirPlay, new SMS sounds ( horrible and way too long ), free Find My iPhone feature and so on.
I know this sounds tempting, but don’t you dare updating your iOS device if you need to jailbreak or need an unlock. A new jailbreak and unlock will probably hit us soon, so just be patient.
Also, if you didn’t do it already, save your SHSH blobs while you still can…
