Following these instructions should probably not be done by anyone that needs them - installing random packages on your device and running commands as root may brick your device. I certainly take no responsibility for anything here. I have not tested the commands, just typed them into this window.

0) Enable developer mode and install wget by installing the Utilities part of the developer mode part of the settings menu
1) Open a terminal and type the following commands:
a) cd MyDocs
b) mkdir get_iplayer
c) cd get_iplayer
d) wget http://harmattan-dev.nokia.com/pool/...o1+0m6_all.deb
e) wget http://harmattan-dev.nokia.com/pool/...+0m6_armel.deb
f) wget http://harmattan-dev.nokia.com/pool/...3.18-1_all.deb
g) wget http://harmattan-dev.nokia.com/pool/...3.04-1_all.deb
h) wget http://harmattan-dev.nokia.com/pool/...o1+0m6_all.deb
i) wget http://repo.pub.meego.com//home:/rzr....9-1_armel.deb

2) Now you have the prereqs, install them. In the terminal type:
a) devel-su
(password is rootme)
b) cd /home/user/MyDocs/get_iplayer
c) dpkg -i *deb
d) exit
(to leave the root shell)

3)
a) cd ~/MyDocs/get_iplayer
b) wget ftp://ftp.infradead.org/pub/get_ipla...er-2.80.tar.gz
c) gunzip get_iplayer-2.80.tar.gz
d) tar -xvf get_iplayer-2.80.tar

4) Now use it....
perl ~/MyDocs/get_iplayer/get_iplayer-2.80/get_iplayer -h
(for help)
or with --raw -g <url> to download an URL

5) setup an alias so you can use it with a few keystrokes (but get this far first)
