Every now and then you come across a piece of software you just can't find anywhere on the internet. This time it's the Ericsson WapIDE.
The tool was free, but it required registration to download, so archive.org doesn't have any copies of it.
I'm almost tempted to just go to the Ericsson offices in Lund tomorrow and ask at the front desk.
