2. Mainboard version is: V1.7_57, 2011-09-28
3. Serial number attached to circuit board: KG31C0601976B (This matches the serial number in the file at \.kobo\version)
4. The additional IC (compared to socketed SD boards that lack this chip) is a Freescale MC13892, an integrated power management IC.
5. The device was manufactured in China (PRC)

I gained some courage and opened my Kobo (it was pretty easy, i used only my fingernails):
0. CPU: imx507
1. there is no shielding
2. Where can I find the mainboard version? I found this number printed on it: UCT(strange font type, can be also WGT)-2 94V-0 1137 E324432
3. There is a sticker with a barcode with numbers totally different from the numbers in the file in .kobo\version (there is another one on the battery, with also different numbers)
4. A socketed micro-SD card is on the board
5. didn't find the origin
and on the inside of the plastic back (printed with black ink on the black plastic, so hard to read), there is a date:20111003
You can find my version numbers in my previous post.
