Help... Jailbreak gone wrong

[nlaksmana]

Jailbreak my iphone 4 with IOS 5.0.1 using redsn0w. I think what happened was I accidentally used the redsn0w for iphone 3G, and now it's all screwed up. Can someone help me? It's now stuck with the black screen with the Apple sign.

Do a system restore in iTunes. Then rejailbreak using the proper iOS tool.

honestly, why give advice if you CLEARLY don't know what you are talking about?

nlak, you might have installed a tethered jailbreak... So you need to plug your phone into your computer, turn in redsnow and select extras, then select boot tethered...
After that you should go into Cydia and search for corona... That will untether you...
Also next time, make sure you have the latest versions of jailbreak tools
