Interesting – I can’t get this to run on OSX 10.6.7. May have something to do with an inability to install *anything* with a .zip extension – not sure how to restore that..

All I get when I click on the app that unpacks from the ZIP is

Actually Sebastian, 3.1.3 has indeed addressed battery issues. I suggest upgrading but I’m just one fish in a huge sea.

I no longer drop from 85% to 20% over the course of a few ticks (unix ticks, seconds). And my battery just seems to last a bit longer… And I’m a heavy user.

I really seems what users see with the 3.1.3 upgrade varies. Just like the Cydia update. =)

Very clear. Thank you Sebastien.
F0recast said I can unlock with blacksn0w and so I did with success. Hopefully there will be unlock for higher basebands in future.
Btw, the icon at my first post was very adequate (to my confusion), lol.

@Tess I’m gonn try to reply to your questions without being too confusing.

What you see on the screenshot is a custom iPhone firmware created with Pwnagetool, which doesn’t update the baseband. So yes, you can unlock the iPhone you see on the screenshot.

In the jailbreak section, I suggest not to update to 3.1.3 because for one there is no compelling reason to, and for 2, if you update directly in iTunes, you will most likely lose all ability to jailbreak/unlock because you will update your baseband.

A tethered jailbreak is a jailbreak that requires you to use a software to start your iPhone every time you reboot. Blackra1n is a tethered jailbreak on certain iPhones, depending on the model.

Hope I made this clear for you.
