Downgrading Baseband 4.11.08 to 4.10.01 is Possible but Can only be Done by “Insiders”

Remember the news we blogged two weeks ago about Chinese hackers were able to downgrade iPhone 4 baseband? It turns out this is being done by “insiders”.

So far no hackers or technology are able to circumvent Apple’s tight security of allowing baseband to be downgraded. Apparently, the only and the biggest loophole here is people.
No matter how secure these SHSH servers are, some “insiders” are able to gain access and perform a “clean downgrade” (no pun intended) without the need to do any hardware modification.

The photo above shows a Chinese customer (not ours) who used this service. He intentionally put a tamper proof sticker and it was proven that his iPhone 4 was not disassemble in any way and his baseband was successfully downgraded to 4.10.01. One wonders why not just downgrade to 1.59.00? Maybe they haven’t found a way yet.
How long will this go on? No one knows for sure. Will it have the same fate as AT&T IMEI unlocking which is also purportedly done by insiders? Probably.
