Angela68 posted this deal currently at 152 degs for a Nokia moby charger: http://www.hotukdeals.com/deals/poundland-signalex-usb-nokia-phone-charger/949106
BUT - Signalex also make various other charger cables on sale at PoundLand (Samsung etc) - the coolest one IMH (well...because I have one) is the Blackberry charger cable that ALSO fits the HTC Desire (and i'm assuming the other HTCs with the same shaped charger adapter thingy)...but - it also works perefectly as a data cable too!
Not sure of expiry...guess when they are out of stock - but they are in there most of the time.
I bought a few to have dotted around home/work/mates (particularly good at work as lots of bods have Blackberrys on the go too) - for a squid a piece - can't complain!!!
