Update: Google has fixed the issues with Google Maps for Java ME and it’s working properly for new installs again.
All the mobile Java versions of Google Maps have stopped working for new installs. When you try to launch Maps for the first time it starts loading the Terms of Service and then fails with the message “Serious Error. Please exit and restart.” Only new installs are broken, if you installed Google Maps before around Jan. 15,l 2013 it will still work. Google no longer supports Google Maps for Java so I doubt that they will fix it but you can report the error and request help on the Google Maps Product Forum.
MGmaps is a passable Google Maps replacement. replacement. It displays maps from your choice of Yahoo Maps, Live Maps or Open Street Maps. This is an old program, no longer updated and some of the features no longer work, including search and driving directions which were powered by Google. Traffic works if you choose traffic.com as the traffic provider in the menu instead of the default Google. MGMaps is supposed to support the GPS on some phones. though the GPS feature didn’t work on my Motorola Rambler

On CDMA QWERTY phones: lock the keyboard in number mode by pressing the Fn key twice.
On iDEN QWERTY phones: lock the keyboard in number mode by doing a long press on the Fn key.
