Hey all,

Just saw this today and thought it was interesting:

Clearly it's unconfirmed, and MuscleNerd/Dev Team hasn't said anything yet. Also, a DFU restore should negate this "watermark", as it wipes the entire phone (it doesn't even let iBoot start up).

That being said...discuss.

Sounds like BS to me. A DFU restore leaves nothing.

I agree. I could see this as something built into the hardware of the phone, but not as something added via a firmware upgrade.

I don't think Apple cares about jailbreaking and unlocking much anyway. They still get paid for every phone.

from an hour ago

False alarm folks, just dissected the iOS 4.1 (downloaded that first before installing SDK), and it's still lockable on iPhone 4. No new encryption based on iPhone unlock check system. But, because of modem firmware change, jailbreak on iPhone 4 will need a little bit more work.

Presumably they (apple) don’t know the exploit for the unlock?
Hopefully this won’t delay the release too much.

How would they as it hasn't been publicly released. Besides, there are reportedly 3 different exploits, Apple isn't savvy enough to find even one until it is publicly released.

That’s what I thought, but read something about geohot holding dev-team to ransom over release times? (poss giving info to apple etc)
 
yea thats what i was thinking too... I just dont understand how it could be possible. Bc when you do a "erase all settings" , that takes everything off including the OS... One thing i have noticed when i have jb'n my phone the last few times, is that this weird water mark line runs across the top of my screen when ios starts to load. But when i completely wipe and put ios back on... It goes away

I would like to hear what everyone thinks-----

That line you saw on the screen was jailbreak code injected into the framebuffer. Which when displayed looks like gibberish
