Can anyone help with a decoding issue?

[Danielm]

Ok so last night i jailbroke my ipod 2g with quickfreedom.
Whenever i try to download anything from an installer source all i get is a message saying "unable to decode package".

Also can anyone point me in the right direction on where to get pocket guitar or a good source for cool apps?

Thanks

use cydia and not installer
pocket guitar is found in the appstore, if I remember correctly

But with cydia for me there is only theme and not decent apps on there and there is also barely anything in the sections if you get what i mean (sorry very new to this)

Why do i keep getting invaled source when i add a repostidy from icatapp.com?

you can add sources... Open cydia, click Manage/Sources

Sorry to be a pin but after i have added a source where do i go to download the apps from the source sections?.

Do you know a working source for pocket guitar?

The link to my repository is http://iappcat.com/r/81037 it says it is a valid source but the apps are not showing i only get a white screen?
