I have just got an iPhone 4 8 GB with below specifications.
I have read lots of bad things about Baseband 04.12.01.Version (or iOS version) : 5.1.1 (9B208)
Modem Firmware (or Baseband Version) : 04.12.01
Network (like AT&T, Sprint, Verizon e.t.c) : AT&T 12.0
Please help me to Unlock and Jailbreak (Untetethered) this iphone. Please provide me links, I am sure I will manage it.
I do not have a Gevey/AT&T Sim, possibly links which do not needs these can help me out.
I have found this link to Jailbreak it, but not sure how to Unlock it.
Please help. I will write a detailed instructions with links once I will get this done. I am sure there would be many newbies like me searching for the same thing.
You need to get a factory unlock in order to unlock it
Can you please help me with some links of the sites you know are genuine and can factory unlock my device ? It would be a great help.
Factory unlock + Abshinte jailbreak

You can't downgrade baseband. the only way to downgrade baseband is when you have ipad's baseband installed on you iphone.
