I have for sale a black MF100 o2 mobile broadband dongle with a PAYG SIM. We used this for 3 days internet access whilst on holiday this summer and originally paid £19.99 for it from o2.
It was really useful - just plugged it into my laptop and it automatically installed the software. You then get the option of buying 24 hour, 3 day or 5 day access (from memory - don't quote me on this as we only bought 24 hours access at a time).
It comes in its original box with all leaflets and the USB cable. The box illustrates a white dongle, but we received a black one inside.
Price includes 2nd class recorded delivery.
PPG or BT.
