If i were to calculate the iPad's amount of RAM based on just the one fact that my iPad App got rejected due to memory warnings twice, and me fixing it, would this violate the developer NDA?
Obviously i know how much memory my App uses, how much the iPhone OS is likely to use and estimate the amount reserved for video memory, then i can deduct from that that the iPad has xxx MB of memory. I just wonder if i can say that number publicly without violating any NDA?
No. Read the NDA. Your not supposed to reveal any tech specs derived from your access to unreleased products.
Just as a matter of courtesy, you shouldn't do so anyway because you can easily provide people with wrong information. There is no guarantee that the products released to developers will be the products that ship to customers. When I was at Apple, I saw major product changes up to 48 hours before ship. One time, an entire line of unannounced products was killed 24 hours before shipping.
Keep your mouth shut. You may not know what you think you know and you won't be doing yourself or anyone else any favors.
2010-4-16 Edit: For anyone reading this in the future, my answer about the NDA was correct. The rest of the answer is just advice based on 20+ years experience in the industry. The down checks are from people who don't like the advice not from people who disagree with answer about the NDA.
If your serious about the software business, you have to be serious about contracts, yes even contracts signed by checking a checkbox in an installer and yes, even contracts signed with giant faceless corporations.
If you don't want people to be cavalier with your contracts and your intellectual property you have to have the discipline to respect the contracts and intellectual property of others.
Of course, that's just my opinion. You're free to lie, break contracts and tramp over other people's property. Just write me in a couple of decades and tell me how that all turned out for you.
