Iphone 4 baseband softmod?

templar

I recently acquired an iPhone 4 and i have been trying to find a software unlock solution for it for about a week now and i haven't been able to find anything for baseband 04.10.01 on either ios 4.3.5 or 5.1.1, and i was wondering if the baseband substitution method for the iPhone 3g could be used with these iPhone too, and in case it could be done, how could i go about it? For any help you can bring me into this matter, i thank you beforehand.
