UPDATE: Tons of updates at end of post. This is it ladies and gentleman, the moment you have been all waiting for, cancel your pre-orders and start your engines – the PSJailbreak open source, free scene solution is out – PSGroove!
If you plan on ordering a Teensy++ know that it has shortages and even more quite soon:
Update, Tuesday, Aug 31, 5:41 PM: We have received a higher than usual volume of orders for this item, and we’re working to ship orders as quickly as possible. Current wait time is approximately 2 days. As of Tuesday 5:41PM these boards ARE IN STOCK. We have enough inventory to fill all pending orders! If we do run out due to high demand, we expect to have more available in approximately 2 weeks, and we will fill any backorders in the order they were received. If you want one of these boards, your best bet is to place an order now. Please understand PJRC is a small company and we are currently running about 2 days to fill orders, though we’re hoping to fully catch up soon!

It should work on:
… and maybe more.
