Note that Quidco suggest on their site that the cashback rate on Panther £15.50 should be higher than I've shown. This has been double-checked with Quidco and they have stated the cashback is on the DISCOUNTED plan amount. See msg 50 for more information.
Orange have indicated that these two packages can support Blackberries at no extra charge. Once you have ordered your SIM on-line (to get the cashback) you will need to contact Orange to clarify that you want the Blackberry version.
