With Apple's rumored media event only two weeks away, people are hopeful that it'll bring an announcement of the tablet. Could it be that the next iPhone OS update is also waiting for that event?
iPodNN quotes a source who suggests that the next version of the iPhone OS is laden with references to its forthcoming sibling, and therefore must wait until the tablet is made public. Last month, The Boy Genius Report pointed out alleged evidence of iPhone firmware 3.1.3 and 4.0 in private testing, which is likely, but these builds have not yet been made available to developers or the public.
Just this week, Boy Genius suggested that the tablet is a sort of "iPhone on steroids," that is to say, a larger and more tricked-out version of the little guy. At the same time, John Gruber relayed one of those "friend-of-a-friend" tales suggesting that the iPhone is actually a by-product of the device they originally intended to build. Only now has the technology caught up to allow for the tablet's existence.
Oh what a tangled web we weave...
