Apologies for multiple posting, but I'd received remarks that I'd posted into the wrong thread, so thought a new thread would be best, and should also help anyone else in the same situation.
I've recently purchased an iphone from the O2 store which was firmware version 1.1.2.
I didn't want to use/activate onto an 18 month iPhone tariff at £35 a month, when an O2 Simplicity tariff (Anytime 15) at £15 a month + Unlimited Data bolt-on at £7.50 a month offered the same deal (except the free Wifi Cloud access).
To do this, I had to unlock the phone to use any O2 SIM, which is the only unlock method available on 1.1.2 OTB at present.
I paid £40 for the method from
http://www.iphoneunlockuk.com
(Ok, naive I know, but I paid, and they're responsible for the accuracy of the instructions they've provided, and any future updates, so I guess I've got piece of mind too)
This involved downgrading to 1.1.1, running iBrickr, activating/jailbreaking 1.1.1, upgrading to 1.1.2 then jailbreaking 1.1.2.
This works fine and I've been using my O2 SIM fine, with EDGE etc.
I have two questions:-
1. This is not technically unlocked as I understand it, as I haven't changed the bootloader at all.
You dont need to unlock 1.1.2 to use an O2 SIM, all you need to do it bypass activation, if you want to use 3rd party apps you also need to jailbreak
Can I safely restore my phone using iTunes back to 1.1.2 provided I have the file?
You can get a fresh 1.1.2 install but read up on Activating 1.1.2 and decide if you want to go through this
or
Do I need to virginize and if so how do I do that ?
All links found apply only to 1.1.1 and earlier, and not OTB 1.1.2.
2. I realise updating to 1.1.3 would now remove all my 3rd party software, would it also lock me out of my current O2 (non-iPhone tariff) SIM?
There is no bypass for activation on 1.1.3 yet DO NOT DO IT
3. If I update to 1.1.3 using iTunes, being as I'm actually using an O2 SIM, would it just return me to the activation screen to setup a new official O2 iPhone tariff?
YES, and there is no bypass for activation so your only route forward would be to take out an offical iphone tariff
Sorry if these are newbie questions, but I don't want to brick the phone
Thanks in advance
