iphone with ipad firmware 3.2.1

[nis002]

i was trying to unlock my iphone (at the time 4.1) by changing the baseband to an ipad's firmware (3.2.1) BUT now my iphone wont turn on. Can someone please help me out and guide me through this mess? Is there anyway that I can change my iphone's firmware(right now its running an ipad's firmware) back to an iphone's firmware?(like 4.1 or 4.2?)

Thanks for your help, greatly appreciated.

You installed ipad baseband or ipad firmware on an iphone 4 ? Anyway, either way will not work on an iphone 4 and you have also voided out your warranty.
