My iPhone 4s is running so sluggishly now I'm preparing to get something else. I'm kind of bored with the whole smartphone thing and am looking at getting an old candybar type device. I know they still make these today and can be had for as little as £10 from supermarkets, but I'm looking for something a little better and nicer in design. Most of these came from the 2008-2011 period and I'm wondering if they would still work today. All I want is the ability to call and send texts, but I would like to use the sim from my iphone as it has all my contacts etc. This phone is gorgeous - it fact it's a work of art - but even if I could find one, I'd need to know it would still function today.
