Here we go again with the iPhone, Apple says it's issuing a fix without - as is Apple's habit - telling us what it's fixing.
Even as a satisfied user I can think of plenty. Searchable e-mail. MobileMe that really works on my iPhone (it still does nothing outside theb e-mail). A way of using the thing that doesn't demolish the battery before you've been out for a whole day. A do-list function for the phone that syncs with the do-list on iCal.
I suspect we're in for nothing as dramatic. Which is a shame.
