A while back I asked around for recommendations for mobile phone repair shops in Cambridge who could fix a cracked screen on ghoti's Nexus 4. At the time we didn't really get many good recommendations; we'd already tried Cambridge Laptop Repair on Arbury Road and been dissatisfied for various reasons; so I went into town on my day off on Monday and had a look around. Carphone Warehouse would have had to send it off somewhere else and quoted 14 days, but when I asked them for recommendations they said that Timpson on Petty Cury have started doing mobile phone repairs. I went there, they seemed helpful and competent, managed to get in touch with their supplies department to ensure they had the part despite it being just before 5pm, and we got it back today apparently now working fine. Not perhaps the cheapest possible (£140), but I'll take that for getting it done reasonably quickly and well.
