Ipad Customers Pay After First Upgrade
Apparently ipad customers will get one free major os upgrade for free but will be charged for os upgrades after that. That has also been the case for the ipod touch.
Iphone customers are not charged for the software upgrades. This has to due with legal accounting requirements according to Apple when explaining the reasoning behind the iPod Touch’s policy.
Normally the fee is around $10.
“Apple will provide you any iPad OS software updates that it may release from time to time, up to and including the next major iPad OS software release following the version of iPad OS software that originally shipped from Apple on your iPad, for free. For example, if your iPad originally shipped with iPad 3.x software, Apple would provide you with any iPad OS software updates it might release up to and including the iPad 4.x software release. Such updates and releases may not necessarily include all of the new software features that Apple releases for newer iPad models.”
