The real deal here is that orange are offering increased cashback of £15.60 for the next 4 days. They also have a sale on phones which mean the Sony Ericsson Xperia X10 Mini Lime is £99.99 (£20 top-up required). Going through quidco means it will only cost £103.
Other deals include -
San Francisco + £20 top up = £114.99 (£99.39 via quidco)
BlackBerry® Curve™ 8520 + £20 top up = £119.99 (£103 via quidco)
If anyone can spot any other worthwhile deals I will add it to the list.
