Thanks also to this company who actually did the work, and also replaced my iPhone screen when it cracked a few years back. As it is, this iPad repair I've been sitting on for about a year - it broke when I dropped it on the floor at the Suzanne Vega gig in Dublin last February. During the wait, I'd looked at the possibility of getting it done by a little company (I want to say it was a branch of Timpsons, but maybe not) that's next to our local big Tesco, but when I asked they charged about twice the rate of Lovefone, and would have had to send it away for a while to get the replacement done. Whereas Lovefone did it same day, and provide a not-terribly-expensive courier service for people in London who can't get to their premises. I can't recommend them highly enough for anyone I know in London who has iPhone, iPad, iPod touch, Samsung or Google Nexus devices that need screen replacement.
So yeah - am feeling pretty happy. And iPpy the iPad is looking good as new. :-)
