I am realizing that some other people had similar issues but it is not quite the same. I have installed couple of applications from Cydia and has no issues with it so far. However, majority of applications I tried installing do not show up after the install i.e. there is no icon for it on the springboard. Those applications can only be seen under manage\packages (but can't run it ). No error messages. For example, no issues with installing iBrowse, FileViewer but no icons for iFile, WildEyes, Search, Searcher... Before the jailbreak (which went pretty smooth) I did restore with itunes to 3.0 and then used redsn0W ver.0.8 to jailbreak with the same 3.0 firmware. Thanks for help. ------------------double post merged------------------For those who have the same issue - I've installed the Poof and brought the icons back.
