Mark it on your calendar as confirmed by Jim Dalrymple.
Rumours of what's to be announced can be found at imore.com, & allthingsd.com among others places, but the gist of it is:
- New iPhone (the name will just be iPhone, just like the iPad)
- iPad mini
- iPod touch refresh
- iPod nano refresh
- Smaller dock connector
So if someone asks you if they should buy a iPhone 4/4S between now and September 12th, you can send them here and say to wait until September.
