Apple announced in March that it would beef up security, include support for Exchange ActiveSync, and release a software development kit (SDK) for the next version of the iPhone. At that time, a TechRepublic poll showed that about 50% businesses had iPhone users while only 27% of IT departments supported it.

With the release of the much-anticipated software update for the iPhone coming this month, TechRepublic is polling IT professionals to see if the new enterprise-ready features are enough to convince their IT departments to support it.
