Now that the iPad is out and iPhone OS 4 has been announced, it looks like Steve Jobs is taking a little time to catch up on his email -- in addition to taking up the new SDK rules, it appears he's very tersely confirmed what we sadly suspected all along: the first-gen iPhone won't get an upgrade to iPhone OS 4. That makes a certain amount of sense, given that Apple's subscription accounting model for the original iPhone only booked free upgrades for 24 months, but really, that's just paperwork -- we don't see why Cupertino couldn't at least allow for an iPod touch-style paid upgrade, especially since the upgradeable iPhone 3G runs essentially the same hardware. And let's not forget that first-gen iPhone owners paid more or less full price for their devices, so if this is true, Apple's summarily dead-ended a $400 phone just under three years after it launched. Of course, none of this is officially confirmed yet, so anything can change -- we've pinged Apple for comment and they haven't responded yet, but we'll let you know what we find out.
