I’m really not sure how the world functioned before the internet. My guess is trade secrets and internal memos were actually kept secret for the most part. These days, however, it seems that everything is public knowledge within a short amount of time. A new leaked memo found by The Boy Genius from AT&T shows us a few of the finer details about the iPhone 3G that you might have been wondering about. Hit the jump for a list of the most notable details.

• iPhone 3G will be activated at point of sale when the device is purchased in store.
• Return period has been changed from 14 days to 30 days
• $199 and $299 pricing is for new activations or qualified upgrades with a 2-year agreement
• 2G iPhone data rate plans will remain available for 2G device suntil further notice
• The new iPhone 3G data plan is $30/month and includes unlimited data and visual voicemail
• There is not a no commitment price. This means you can’t just walk in and bang $500 on your credit card and walk out.
• If you are an existing iPhone customer in good standing, you will be able to extend your contract for two years when the iPhone 3G launches and get the ill-na-na $199/$299 price point. Doesn’t matter when you bought an iPhone either.
• AT&T and Apple stores “unbrick” the iPhone 3G at time of purchase, but for some reason if that doesn’t happen, you’ll be required to use iTunes at home.
• Pre-paid and Pick Your Plan will not be allowed on iPhone 3G
• Device purchase limit remains at (3) per customer in AT&T stores.
• 2G iPhones to remain as demo models in AT&T stores “until further notice”.

• Launch day will mirror last year’s launch. This includes extended store hours, crowd controls, etc. Security will be provided to stores requesting armed police or guards.
• AT&T is working with Apple to roll out GPS-enabled applications.
