Hey Guys,
I followed the advice of musclenerd on twitter who advised to use redsn0w for those having trouble installing cydia after the GP jailbreak. I too could not get the loader program to install cydia. So, I used redsn0w after GP and only had "install cydia" selected in the options and it installed cydia and everything appears to be working fine. I had to chase down redsn0w but I used the most recent version I could find (0.9.7, I believe as I am at work right now) which is not on the main dev-team page. I saw many credible folks on twitter saying this method is fine and so far so good.
link to that version ?
just tried 0.97 beta 6 and when i run it .. it says to select the ipsw file before i can do anything else which i dont have
