So I got this beaufitul 3GS in ebay, fairly cheap and in good condition, locked to 02 , and with iOS6 and baseband 05.16.07. I am a complete noob (first apple product) so I needed to sweat blood for a few days before I learnt that I needed (in order to unlock the device to any carrier) to downgrade using redsnow the ios to 4.1 , flash the baseband to ipad's 05.13.04 in order to be able to use the cydia exploit (ultrasnow) that gets the trick done. Done all that, and a few headaches later, I need to re-upgrade the device to a more useful iOS (such as 5) while preserving the baseband/unlock. I haven't find anywhere a step by step tutorial on how to do so , and then I ended up here, which seems the right place. Thank you and greetings from Scotland! |
