Sorry for not replying sooner; this never appeared in my quote notifications. Anyway, OTA stands for over the air, as in the updates performed from within the settings app. Apparently, jailbreaking disables OTA updates so the users' jailbreaks aren't undone without them knowing via software updates. On the off chance that you can get it to update, the jailbreak will be undone or dysfunctional.OTA? And why not?
