[EDIT: Nov 16th] - ok, 2.7.1 users can run sh now, this thread & posted zip file is for 2.7.0 users only
I installed ipdf rev. 5. scotty1034, brilliant as usual.
Yes, it's much faster. Ugly black bars [pdf bounding box] are gone...
Installation of scotty1024's ipdf rev 5 for other dummies like me
what you need- 2.7.0 firmware. if you have udpated to 2.7.1, it won't work for you.

- STICKY: You already installed the feature to run shell scripts by clicking on files with the ending .sh in contentlister. Doing this installation is called [SHELL] hack here @ mobileread.
If you didn't already install this feature, you have to do this before you can install ipdf.
In this thread is described how you can install the [SHELL] hack.
[EDIT] I have posted a »step-to-step-guide to do the [SHELL] hack« there.
Again, if you have 2.7.1, you will not be able to install the [SHELL] hack.
- ipdf5.sh.zip downloaded
what you have to do- Extract ipdf5.sh.zip [files ipdf & ipdf5.sh] to newspapers folder of iLiad's USB drive.
- Unmout iLiad's USB drive, press iLiad's "news" button
- Click on ipdf5.sh
- Green Lamp blinks. You see a new entry "xpdf.orig" [a back-up copy of xpdf] in Contentlister. Blinking stops. This it was. [no reboot needed]
what you get
a faster pdf viewer.
Any risks?
No risks, I think. I used ipdf5.sh & got no bricked iLiad. er_registry.txt was not changed.
Contents of ipdf5.sh
Code:
cd /usr/bin
cp xpdf /opt/content/newspapers/xpdf.orig
mv xpdf xpdf.orig
cp /opt/content/newspapers/ipdf xpdf
