If you're about to buy your first smart phone, it might be a much better idea to start familiarising yourself with Android or Windows Phone, which can both be found on cheap devices and offer more sophisticated features, and more intuitive interfaces.
The Curve 9320 is evidently aimed at the budget-conscious, first-time smart phone buyer, but it's genuinely hard to recommend a phone which runs on an operating system that's on it's last legs. The Curve 9320 is available on a monthly contract with prices starting from as little as £7 per month. The inclusion of a dedicated BBM key suggests this phone is designed for messaging addicts, and you'll also find BlackBerry's popular instant messaging tool built into Facebook and Twitter, for instant sharing on the go. The BlackBerry Curve 9320 is an entry-level smart phone that packs a 3-megapixel camera and the latest version of the BlackBerry OS.
