I've been giving some serious thought about buying a decent mobile phone (US: cellphone) with current Java capabilities. First of all, I started by looking at my local vendor pages and then looking for more detailed information about specific phones. It can be a lengthy process. However, since I knew I wanted Java capabilities, I wondered if the J2ME pages had more information and sure enough, they do. Here are some pointers I found useful that might get you started if you are thinking of developing for the increasingly powerful small devices via Java:

• J2ME package names, across all of the profiles of J2ME
• Combined with the J2ME survey article, you can orient on the different options (the graphic below comes from this)
• The J2ME Device registry is a great way to search for devices that offer the profile you need
• The J2ME FAQ - pretty darned useful
• The main Java Mobility page has all the other pointers you might need
• After you get an idea what you want to do and which profile you want to target, then you need some decent tools to get productive: NetBeans 4.0 includes the NetBeans Mobility Pack with support for J2ME development (MIDP 2.0 and CLDC 1.1, including code obfuscation, and it integrates with the J2ME Wireless Toolkit 2.2) - perfect
