just a quick note about MNPlight - I had problems with installing the package as the URL is not recognized by Installer app.
So what I did...
1. I downloaded two files
onto my local drive.
1a. Renamed "repository.list" into "repo.list" (not necessary obviously, don't know why I did that... )
2. Inside repo.list there are 3 links pointing to source files at http://iphone.lefessant.net/..... I changed the links into http://127.0.0.1/repo/.... so that MNPLight one looks like
2a. Copied both files into //var/root/Sites/repo/ on my iPhone (I created "repo" manually)
3. Added a source in Installer http://127.0.0.1/repo/repo.plist and got two new categories MNPLight and MNPgoodies.
4. The installation of MNPLight was completed successfully after a couple of tries (I cleaned the installing queue as well) and I got Safari running with 127.0.0.1:2007/ opened.
I don't have time to check if it's actually WORKING but prolly this will help installing it.
