Downgrade problems: 1.1.1 with 04.02.13_G??
I need some info and quite possibly some help. I have a OTB 1.1.1 which I bought from the US in October and I JB'd it using jailbreakme.com and then anySIM 1.1 to unlock it so I could use it in Cyprus on the local Cytanet/Vodafone network.
After the unlock, I threw away the ATT sim card that came with it, and the phone was working fine in 1.1.1 with BB 04.01.13_G . Last week I decided to upgrade to 1.1.2 using octoprep and then foolishly to 1.1.3 using the official dev team release. The upgrade did not go very smooothly so I wanted to downgrdae back to 1.1.1 and start again. I did the proper downgrade in itunes and I am back to 1.1.1 but I noticed that my firmware is now 04.02.13_G. My question is
(1) can i jailbreak/activate a 1.1.1 with 04.02.13_G using jailbreakme.com and
(2) can I do it without using the original ATT sim card?
