I just got my iphone 3gs yesterday running the iphone 4 version. I unlocked and jailbroke it for my t-mobile service and everything was going great until i decided to start downloading themes and i messed up. I downloaded winterboard from cydia and i downloaded and installed this batman theme and now i get no icons just the time/date. I can control the volume and can receive messages as well as receive calls but i can't do anything else. Any options? Am i posting this on the right thread? If i didn't sorry about that. Any help would be great though.
I take it you can't access winterborad app or settings...
You can try installing iphonebrowser (its a program you can explore the phone with, google is your friend here) and navigate to Library/Themes and delete latest theme; the theme might be the problem.
edit*
after deleting reset the phone by holding sleep + home button at the same time, keep holding after the phone shuts off untill you see the apple logo.
Guys thanks for all you help. I took the easy way and restored and redid everything. No big problem as i didn't really have too much stuff on there but now everything is back to normal.
