iPhone SDK itself. That said, it's hard to ignore a new reference to a "multitasking dialog box" buried deep within the iPhone SDK 3.2 beta that -- while not new to beta 4 specifically -- we're told didn't exist in 3.1.3. Now, the wildest possible speculation would have us believing that this is the very first by-product of a new multitasking system for developers that's being developed for the platform, presumably destined for an appearance in OS 4.0 when it's introduced along with new hardware this summer -- but it's just as likely that Apple will continue to keep the iPhone's multitasking capability to itself, a function it uses liberally among the phone and music apps, just to name a couple. For what it's worth, AppleInsider is citing a tipster claiming that Apple's got a "full-on solution" to multitasking that would properly address its main concern -- battery life issues -- for release this year, so maybe we'll be able to chuck those awful push notifications before we know it. Now if you'll excuse us, we'll be over here in the corner running a few dozen apps on our Pre Plus.
