Always good to be suspicious of the claims of $91 camera vendors. I'm not saying they're misleading anyone, but I'd bet it's a patched Chinese camera at that price. If so, yes, it's international now, but may revert with a software update.
IMO, the main issue with Chinese tagged cams is the upgrading difficulty. If I bought Chinese cams, I'd probably do the CBX fix just to avoid the time required fiddling with them in the future, but for those who don't need firmware updates or don't mind spending the time, it's not a big deal.
Do the cameras automatically update the firmware?
Shouldn't they work fine as long as you don't update the firmware?
