Wondering if you can help me. Ive had my iphone for a while and its fine. But im not up to scratch with what I can now do to upgrade further. I had an OTB 1.1.1 downgraded it to 1.0.2 and then unlocked it with IPSF v1.6. How can I upgrade to 1.1.1 or even 1.1.2?

just download oktoprep on 1.1.1 upgrade to 1.1.2 and jailbreak/activate. IPSF survives the upgrade.

If you are in a country other than one where iphone is offically released then download iworld through installerapp to fix the phone/sms crashing problem...

Should work. I have IPSF unlocked phone and thats what i did...everything works 100%.....
