I received a brand new Motorola RAZR V3xx Phone<\/a> that is branded by Cingular, and they have set the J2ME (JVM) environment so that 3rd party j2me\/java applications (such as Google Maps) are not trusted to use the network. Unfortunately, this means that every time I move Google Maps it pop's up a dialog asking me if I want to let it use the network. This completely ruins the user experience.<\/p>\n

Browsing the web, I found out that if you delete a file from the phone a\/mobile\/certs\/root\/x509\/kjava\/j2me_domain_registry.sm it will fix this problem, but keep some of the built in (signed by Cingular) applications such as mobile email from working. Since I didn't want to use built in applications, I decided to remove the file (after backing it up!).<\/p>\n

The hardest thing was to find out what software to use to access the file-system on my phone. After trying several options, I settled on the latest version of p2kcommander <\/a> (4.9.8, earlier versions didn't work for me) and the p2k usb drivers that are  available on the Motorola developers website.<\/p>\n

This combination of software allowed me to edit the file-system and remove the j2me_domain_registry.sm file. (it also allows you to add files to the file-system, such as your favorite skins, mp3s or MIDI ring-tone). <\/p>\n
