The Research in Motion Blackberry 7230 is a PDA phone of decent, but not outstanding quality. I have been using it for a number of years now, but the most I have really appreciated was its high quality keyboard. It was far easier to type text messages with one of these rather than a standard phone keypad. Being one of the older Blackberries, it does not look like its going to win a beauty contest, but then again, it was made for use as a business phone. The display is of OK quality, and there is excellent battery life, provided you have a case that powers the screen down while it is inside. Reception was very good for a phone that had no external antenna. As for extra features and applications, there really are none unless you pay for a Blackberry Connect data plan. There is no other way to put third party applications on it, so that is quite an issue for someone who doesn't want to shell out for an expensive Blackberry Plan, especially when you could do more for less with an alternate smartphone. Nowadays, it is more of a phone for beginners to the smartphone market, but because they can be had on eBay unlocked for ~$60, it is a good buy for a smartphone on a budget when your plan is not yet up for an upgrade from your wireless company.
