Now he's stuck with his iPhone 4 and the only way he can turn it on is by pressing the lock button about several hundred times. Sorry, but it sound like you have a similar problem and it's not Apples concern because you Jailbroke your phone and they don't cover for that. Hope this helped :p
If you are in the same position as this guy, and you actually still have warranty on you iPhone then you aren't screwed at all!
Just open the back of the iPhone, take some bleach and tap it on the 3 water damage sticker which are in the USB port, Headphone jack, and one is on the motherboard its a triangular one. If your phone wasn't thoroughly water damaged then the triangle one should stay white. You do have to open the phone because there is like a glass or transparent film that covers it from the out side. But seriously one lil tap of that bleach and your good. Then just take it to genius bar say that its acting up and pretend its a hardware issue if the question you a lot (which they wont). Just act retarded and not tech savvy at all lol. and you should get a new phone.

you are some what screwed if you do not have that year warranty. If you don't have that warranty then your best bet is to open the whole phone and replace the home button and get that shit into DFU and restore. Sadly you wont be able to jailbreak considering there are no use of SHSH blobs atm. so yea bud...

No he is not, there was a method somewhere, but i can't remember, try googling your broken button problem.
I cant recall it either, but im pretty sure the phone was to be working in order to get that phone in DFU without the home button.
