I'm bout to put my moms old iPhone 4 on ebay lol. How do I JB / Unlock this piece?
 
Depending on what firmware its on and baseband version.
Also if you have shsh blobs or not for any firmware prior to 5.0

Oh. Darn. There's no simple one click method anymore I suppose. I JB'd my old iPhone 3S before selling it and that was easy. Seems more complex these days :(

Nope, with every new iphone and firmware version Apple makes JB harder and unlocking even more.
The old iphone 2G and 3G JB days are over since Apple stepped up their game with Shsh blobs and other security checks.
