I got an iphone 3g (2.0.2) about a month ago and love it. I jailbroke it 2 days ago and everything was fine. Last night 2 things went wrong:
installer stopped working- it tries to connect, but says "error can't find host". It worked before and cydia is still working. the other (bigger) problem is that i seem to have lost the ability to connect to the internet unless i am on a wifi network. i get a "safari can't open the page bc it is not connected to the internet" message. I have no idea what happened (but i noticed it after i downloaded boss prefs- fyi).
I didn't sync and upgrade with itunes or anything like that--
someone please help!!!
