Thanks to this thread I decided to be brave (or is it stupid?) and try this on my newly acquired PW3 running 5.8.11
- Is this a new device, never connected to the Internet? Yes, but I did connect with the internet. S/N: G090 G105 7*
- Is it a "refurbished" device? Yes
- Is this the firmware it arrived with or has it been updated to this version? Stock 5.8.11, I downgraded using update_PW3_5.7.4_initial.bin
- Is it registered? Yes
- Does it have ads (Special Offers)? No
- What country was it sold in? US
- What country was it delivered to? US
- Was the seller an on-line Amazon site or was it a third-party seller (on-line or brick&mortar). Amazon (US)
Everything was successful, I am now on fw 5.9.6.1 (3314460001) and jailbreak is still in tact.
