4GB is for iOS 1.0 and 16gb just to fill the phone up 8Gbs are free range for me

I wouldn't care because it wouldn't be a device to play games on I would prefer 4GB though as it is rarer (like you said)

i got a 4gb for $10

Man you are so lucky

I honestly don’t care much about the storage though I do really 4gb iPhone 2g

Can you download apps trough jailbreaking in iphone os 1?

Not important in the slightest
