If you’re a fan of low-cost messaging phones with a social twist, prepare to lose your mind, for Nokia today announced three such devices in the C3, C6 and E5. The most basic of the bunch is the C3, which just so happens to be the first Symbian S40 device to ever feature a full-QWERTY keypad. It offers a 2.4″ QVGA display, 2 megapixel camera, Wi-Fi, Ovi Chat, Ovi Mail and support for microSD cards up to 8GB. It will be be available in golden white, slate grey and hot pink in Q2 for 90€ ($122 USD). Next up is the C6. A full touchscreen with a sliding horizontal QWERTY keypad, the C6 bring to the table a 3.2″ 360×640 display, 5 megapixel autofocus camera with flash, HSDPA, Wi-Fi, GPS and Ovi Maps. Look for it next quarter for 220€ ($299 USD). Finally we have the E5. Expected to be available in Q3 for 180€ ($224 USD), it crams a 2.4″ QVGA display, 5 megapixel camera, HSDPA, GPS, Wi-Fi and support for Microsoft Exchange and IBM Lotus Notes into its tiny candybar frame. As always, we’ve got Nokia’s little promo videos queued up after the break.
