I am not very familiar with Symbian OS, which is what I assume your Nokia is running, but the only way that really comes to mind is someone could intercept your info, including password, while you are using a WiFi connection. This is a real possibility if you are using public WiFi, and are not paying attention to the connection name or you are unfamiliar with it, and a black hat has set up an open connection called something that seems harmless and plausible. Would you use a WiFi connection entitled ATT Wireless or CoffeeShop Wi-Fi that is unencrypted and doesn't ask for a password while you are out of the home/office? If so, there is a chance that the connection isn't actually AT&T or CoffeeShop, it's really that dude in the corner with the rad laptop, and everything you do is exposed to him. I hope your question is just theoretical!
