It’s that time again, folks: with another two weeks behind us, Apple has released yet another Beta rendition of iPhone OS 4. Like those that came before it, this fourth Beta release is signed and sealed for developers only — in other words, if you’re not a dev, you’ll have to sit tight for a little while longer.

If Apple’s development cycle for iPhone OS 4 is staying true to major releases that came before it, we should be quickly approaching the final build. Apple rarely exceeds 6 or 7 Beta releases — so chances are, we’ll see OS 4 ship out to everyone within the next month or so.

Folks much smarter than yours truly are hard at work tearing apart this latest Beta for all the hidden morsels, so we’ll let you know if we hear anything.
