Few days ago i installed IOS 4.1 on my iphone i jailbreaked it(redsnow)and installed bootlace app and turned my iphone to android.Yesterday i decided that i didnt liked the android and erased it and now my iphone goes to choosing screen on opening if I choose android or console nothing happens if i choose apple logo it just goes in a black charging screen if my iphone is plugged if its not it just turns off.When i plug my iphone in my computer itunes doesnt recognize it so i cant restore it.Sorry for my bad english.I googled this but i couldnt find anything helpful.Any one knows a solution for this.

Connect to computer, hold power and home buttons for 10 seconds, release power button, keep holding home, iTunes will ask to restore.

Side note, this is decidedly covered in the iDroid forums and FAQs that you should have read before installing bootlace -- any time you're doing something like this, I thoroughly recommend you familiarize yourself with the developer's FAQs -- thankfully this is an easy fix, but it's worth it to know in advance.
