Free Memory

The WS003SH has 64MB of RAM, where about 20MB are used by Windows, leaving 43.62MB "free". Another 27-28MB are used by the system (device) memory. This leaves around 14-17MB memory available to the user.

Because the phone module is useless outside of Japan, you can stop its processes and thus gain additional 3-4MB of RAM. 21MB are much more than 17MB on a low-power device as the W-ZERO3 :)

To stop the phone services, I used SKTools. Go to the Today Plugins module and from there disable the Willcom services. Try disabling all items with Japanese names; these are the DLLs they relate to: shwmailstatus.dll, shcallstatus.dll, shlightmailstatus.dll, shphonestatus.dll). Then soft reset.

UPDATE:After a hard reset I decided to take a different approach at customizing my W-ZERO3. First of all, I used my own localization method (see Forum), and then, I decided against using SPB Pocket Plus. Although quite convenient, the latter seemed to consume quite a bit of RAM and now I get an average of 19.5-20.0MB of free RAM, increasing to the previously unattainable 22.3MB free after a soft reset.
