Motorola i90c is for all intents a general purpose computer, with memory, CPU, and I/O. Java apps on cell phones run in a “sandbox” that prevents them from doing damage to surroundings. I’ve used my Nextel Online service to download Java applications, but no one has yet hacked me via a malicious Java application. I downloaded, installed, and ran the app, and eventually found myself downloading a 4 MB file from Motorola. If you’d like to update your Motorola cell phone, you need to know what version you’re running.”]
