firstly, i use pdanet to tether internet on my desktop. everything works as far as internet goes, however i cannot log into facebook for some reason.., wondering if its conflicting with with my facebook app or some security issue, it fails to load data and soon the browser acts like its no internet when there is.

secondly, when i load up cydia it tries to download what ever it is at the top of the screen and about 15 seconds later i get error message and have to press ok and move on to browsing cydia, trying to find a cure for the lil error. dunno the issue but if someone is willing to one on one with me in troubleshooting it would be nice.
