Default Bootloader hacking details

I thought I would answer some of the more common questions I've been receiving.

Is that the AT&T-branded Galaxy S4?
Yes. It wouldn't be very interesting otherwise.

Does this allow you to run custom kernels and recoveries?
Yes.

When will this be released?
I will not be publishing anything at least until the Verizon-branded Galaxy S4 begins shipping (late May).

Does that mean it will work on the Verizon model?
It is highly likely this will also work on the Verizon model, but since I don't have one I'm unable to test at this time.

Will bothering me result in an early release?
No.

Is this the result of a leak?
No. I would not associate myself with the publication of confidential materials that are proprietary to these companies, regardless of the fact that I disagree with their policies on device openness. Plus, where's the fun in that?

What about the bounty?
Feel free to wait until I publish and decide for yourself if it meets your criteria. As always, I prefer any donations go to a reputable charity organization instead of me, but I won't refuse if you insist on throwing money at my PayPal (http://goo.gl/zBGb0).

Is it safe to install OTA updates?
If you are interested in taking advantage of this release, it is recommended that you avoid installing OTA updates until it is published. Please be aware that refraining from installing updates may prevent you from receiving security and stability fixes for your device, and consider whether this is a risk you are willing to accept.

What's your favorite color?
Blue.

Thanks from all the current and future S4 owners, of which I am not one. But I know a gift horse when I see one.

That's extremely good news. Thank you very much for your work! Just picked up my AT&T GS4 today...

I of course respect your wishes to release/share (or not) at your own schedule, it is your prerogative; but may I ask, why the wait for the Verizon model? To be clear, I'm not in any hurry, I'm just curious...

Also, any technical updates on how you made this possible? (other than obviously a good knowledge of ARM and reverse engineering)
- Samsung Galaxy S 4 (SGH-i337) -- Custom i9505 build | KT's latest i337 kernel | Primary Phone
- Samsung Galaxy S II (SGH-I777) -- CM 10.1 | Kernel Varies | Backup Phone
