IBC Exhibits open on the 6th of September, opening at 10:30 AM on that day and at 9AM for the rest of the exhibit days. The last day is the 11th, with a closing at 4PM.
Conferences begin a day earlier and finish on the 1th as well.
The IBC is offering an iPhone/iPad and Android App again this year. In just the first few minutes with it, it seems better than last years, although it doesn't have some of the same problems. There doesn't seem to be an interface with the iPhone/iPad/Android calendar system...though the yellow star that chooses favorites is a decent touch for both choosing and creating a list of events and exhibitors. Still...what I would give to have the info like the location pass through to my calendar.
