Research In Motion has just released a 3G BlackBerry Curve in pink, officially called Fuchsia Pink. This phone has the same features as the original black version, with a 2MP camera, 2.5" (dia.) color display, and 320x240 TFT LCD.
This may well be the perfect Valentines gift. I know I would prefer it to chocolates. Other features: WiFi technology, BlackBerry push technology, VZ Navigator™, Visual Voice Mail, V CAST Music w/Rhapsody and V CAST Video on Demand, Mobile Broadband Connect.
I only found it available through Verizon in pink, but I'm sure other carriers will be following shortly.
