  • 30GB iPod: This can be either a 5G or 5.5G iPod. To distinguish the Fifth Generation iPod (Late 2006, 5.5G) from the original Fifth Generation (5G) iPod is by comparing the last three digits of the serial number. The Fifth Generation iPod (Late 2006, 5.5G) serial number's last three digits will be one of the following: V9K, V9P, V9M, V9R, V9L, V9N, V9Q, V9S, WU9, WUA, WUB, WUC, W9N and X3N. The Fifth Generation U2 Special Edition iPod (30 GB Late 2006) serial number's last three digits are W9G.
