I'm on my third CLNR Thunderbolt (first one wouldn't hold a data signal other than 1x and the second one had a non working microphone). I was just poking around in the settings menu and I noticed something funny.
The serial number reported by Settings -> About Phone -> Phone Identity and the serial number printed on the sticker under the battery don't match. The one the phone is reporting starts with "MB" while the one under the sticker starts with "HT". The numbers afterward are completely different too.
The phone seems to work fine but differing serial numbers seems a bit fishy to me. Does anyone know a reasonable explanation for this?
