I have been using 'Installer' on my iPhone for a while now but I updated my sources this morning and it came up with 8 updates. I updated these and now Installer still says I have 7 'updates' to install. When I look at these, they are actually downgrades e.g. it is showing Ringtones version 2.86 when I already have 2.87 installed. How do I stop this happening?
