It's seeming more and more to me with every bout of forum bickering that '4S' is a codename.
It sounds too dumb in everyday conversation, and it'll sound too dumb on the stage Tuesday morning.
So, why is '4S' so prevalent? Even going as far as being in the recent iTunes betas?
'Successor'. All it most likely means is the '4S' is the successor to the iPhone 4. For all we know it could be called the 'iPhone Derp'. It could be anything from 'iPhone 5', to 'iPhone V' (Which actually sounds kinda alright)
However, back on topic, I want a 64GB. After checking how much media I have exactly, it comes out to 60.3GB. I can leave out the videos, since I've seen them all already. That'll shave it down to 39.5GB. As my music collection grows, it would be the phone that I actually end up keeping for years, instead of random upgrades when I find a cheap one (January I got a 16GB 3G for $60 with a shattered screen, replaced every part except for the chrome bezel and the logic board, then July I found my current 8GB 3GS at a pawn shop also for $60). I'm not going to deal with the data usage for iCloud, battery drain of constant 3G streaming, etc... I really hope this rumor to be true.
