Wow! So the iPhone 2.0 Firmware has already been leaked. Today both Macrumours.com and Gizmodo.com are reporting on how to download and install the software. Reports also say that this update does not work for all the iPod Touch users out there, sorry. For all the Swedes, 99.se/iPhone did a thread about this just recently as well.
Interesting reading. A couple of people have already updated with success, but I’d say that waiting a couple of days is probably smart in order to see what the exact effects are in terms of Jailbreaking etc. Most importantly, don’t forget to backup!
