After JB my 4.2.1 safari - cydia not working

[f4780y]

guys - - need help here... have iphone 3GS 4.2.1 BB 5.10.04.

tried jailbraking it with redsn0w with BB upgrade to 06.15.00.

now the cydia is launched but its not working and showing only a white icon.

What to do...?

current BB is 6.15.00

Why not head over to our sister site, iphoneforums.net? There is a link on the top right hand side of this website.

Since you are JB a phone with a non-standard BB, you are likely to get much better support over there as there should be other users with the same setup.
