Hi Darren

There is a difference between mini-usb and micro-usb (newer (host/device)) type. Any power supply capable of supplying regulated 5V @850mA (ideal) 700mA min with a Micro-USB plug would be fine.

Judging by some of the comments on the official RasPi forum, you may want to spend a little more and avoid ebay, or at least the very cheap versions.

If you have a modern mobile phone, it is highly likely that the charger for it will work with the Pi, as this was the reason they chose this power source in the first place.

I have a charger for an HTC desire and a second one for the Samsung Galaxy SII and they are both rated at 5V, 1 amp which will be fine.

Yes, iPhone power adapter should work fine. I believe the genuine Apple one is rated at 1A. If you have something other than the official Apple one, get out your microscope and check the rating label on it.

While we are here, it's worth mentioning that you should probably be a bit careful with the USB cable you use. I have found that some micro USB cables are inadequate for charging phones (although they are fine for data transfer), so I would expect them to be inadequate for powering the Rpi. The problem cables have been very cheap ones, or thin flat ones on a winding extender gizmo. Blackberry micro USB cables can be found fairly cheaply on an auction site near you, and I've found them to be very good.

Following on from my previous comment, the same goes for USB extension cables. I've found that cheap ones are no good for powering/charging devices. So for powering the Rpi I would recommend sticking to USB cables and extensions from one of the well-known cable or phone manufacturers (Belkin, Molex, HTC, Motorola, Samsung, Blackberry, Sony etc.).
