The 4" Galaxy S3 Mini might be the phone for you. With the smaller size and packing the same punch as the main S3, it's a clever move by Samsung to cater for individuals such as yourself, at the other end of the market.

There’s also a 5-megapixel rear camera with LED flash, autofocus and 720p video capture plus a VGA front-facing camera, WiFi 802.11 a/b/g/n, DLNA, WiFi Direct, WiFi Hotspot, Bluetooth 4.0, NFC, microUSB 2.0 and a 1500mAh battery."
I stand corrected, but for anyone wanting a smaller phone the Mini might be the phone for them. I'm all for 'bigger is better' and will be getting the Nexus 4 when it comes out - at that list price, you can't really go wrong.
