Why no 3.00? Likely internal builds (3.00, 3.01, 3.02) used for PSP-2000 (Slim) factory testing / launch preparation. Public launch firmware for Slim was **3.60** (or 3.71 depending on region/date). Version numbering skipped to avoid confusion with 2.80 → 3.xx security line.
Current Best Firmware for Homebrew: **6.61** + **Infinity / PRO-C2 / ME / LME** CFW (permanent on 1000/2000/early 3000; temporary on late 3000/Go/Street).
