In the first picture, pin 30 is clearly labeled, and I can't quite see if pin 2 is labeled
The second picture is a little fuzzy, but it looks like pins 1 and 15 are labeled
So, it looks to me like you've got odd numbered pins on one side and even numbered pins on the other.
Looking at the even-numbered side, counting from the left, you've got pins 2,4,6,8,10, no 12, a dark square at 14, no 16, and then pin 18.
On the odd-numbered side, counting from the right, looks like you've got pins 1, 11, and 15.
So, no, you ain't got +5V on pin 23. What you've got is +3.3V on pin 18. The pinout URL says this:
18 3.3V 3.3V Power (+)
Stepped up to provide +5 VDC to USB on iPod Camera Connector.
If iPod is put to sleep while Camera Connector is present, +5 VDC at this pin slowly drains back to 0 VDC.
