Well, not long after the initial post, I see that SpaceX's website has
an update:

Flight 4 of Falcon 1

As mentioned in my update last month, we do expect to conduct a
launch countdown in late September ? as scheduled.

Having said that, it is still possible that we encounter an issue
that needs to be investigated, which would delay launch until the
next available window in late October. If preparations go
smoothly, we will conduct a static fire on Saturday and launch
sometime between Tuesday and Thursday (California time).

The SpaceX team worked hard to make this launch window, but we
also took the time to review data from Flight 3 in detail. In
addition to us reviewing the data, we had several outside experts
check the data and conclusions. No flight critical problems were
found apart from the thrust transient issue.

Flight 5 production is well underway with an expected January
completion date, Flight 6 parts are on order and Flight 7
production will begin early next year. We are now in steady state
production of Falcon 1 at a rate of one vehicle every four months,
which we will probably step up to one vehicle every two to three
months in 2010.

In the picture of vehicle 4 on the pad there are two red bands on the
second stage I do not recall seeing before.
