We have used MedicAnimal a few times since our Cat was diagnosed with a food intolerance - they are fast, about a third of the cost of buying food at the Vets and completely trustworthy, I have absolutely no hesitation in recommending this supplier.
Just unlocked a iPhone 4S previously on Vodaphone UK, put in the o2 SIM, and using the Wifi - it activated - even without connecting it to the PC.
Service is great, do not get fooled by these unlock sites claiming to do it with software, this is the best way and most reliable way to do a unlock. I highly recommend.
Thank you Official iPhone Unlock.
