Late Monday, Apple release the Gold Master version of its iPhone OS 3.2 SDK, which will act as the final version of the development kit. Per MacNN, developers can also now download the official iPad 3.2 firmware and corresponding licensing agreement with the agreement hints at terms for future firmware upgrades.

“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,” the agreement reads.

While iPhone owners have been permitted to download every major firmware update at no charge, the iPod touch requires a modest fee for similar downloads. The iPad appears to balance both models, providing one major revision at no cost but charging for further updates.

Stay tuned for additional details as they become available.
