LG VM510 filesystem innards, tricks, and treats

[bigsupersquid]

ok, I'm starting this thread because it diverges from the thread topic where I've been discussing this.
I'm getting more specific about methods and things I've figured out here, and posting links to what I've got done already.
first, the root filesystem from my LG VM510, after a hard reset, with the demo games deleted, and two j2me programs installed, is
<sorry, file redacted>
hope nobody has problems with the filesharing provider. I took what I could get without limiting the download quota for everyone else.
the contents of the /root/ams/ folder are a series of numbered folders (/root/ams/xx, where xx is a number >=10,) each of which is either empty except for /root/ams/xx/xxroot/ or contains a java program and its system related files. data for each program xx is stored in root/ams/xx/xxroot/.
in this particular filesystem snapshot, the numbered folders contain the following:
10 mypix
11 twitter
12 myspace
13 facebook
14 vmnavigator
15 uiinbox
16 opera mini
17 google maps
18 contact vault
19 tetris
22 resistor calculator
27 scribpad
next post, when I've got a little more time, I'll describe in detail what I've done to replace the built-in software I didn't want with innoccuous freeware, and specifics on how to get a custom icon to show up on the menu.
enjoy!
