You would be best off making an .osm file that JOSM can handle.

I was asking what phone Nick has, and it's not the most obvious
because most phones that support j2me don't have their wap settings
set properly, at least with the phones I've owned in the past, and a
lot of them had j2me internet access disabled as well, there is
something seriously wrong if you have to hack your phone's firmware
just so you can access the internet from j2me apps.

Smart phones on the other hand were designed to be able to access the

Most people keep their phone charged, it's annoying to remember to

j2me apps won't run on android, won't run on iphone, I'm pretty sure
they won't run on web OS, so in these cases you have no choice but to
re-code, and blackberry is most likely going to have to do something
similar with future releases of their JVM or they'll be looking at
loosing market share to phones with much better SDKs. Maybe Oracle or
MS will keep improving/updating the JVM on WinMo, maybe they won't so
there isn't any guarantees that j2me apps will continue to work on
WinMo phones either.
