Re: Somebody broadcast this TX for me!!!

It doesn't let me there, it says that the input is spent, but it's not, its unconfirmed for 72 hours.

It is.

I doubt that transaction have been there for 72 hours. Fee is 54 satoshi per byte and the input have 40 confirmation and 80 per byte fee. Could be wrong though.

Whatever the case is. It'll be best to let that transaction confirm.

Not that one, the other TXs are the older ones, should I just double spend the other 2 without that one?

That hex you posted spends an input from 633d4aa816d1c077375cea57f05f4a92010c3f52a753823989e820ec478d10fe:1 and edc498a5de0de762de2fbdc06758c87f5c893998a63bd4c4301588847421749b:1 .

You got the input transactions wrong.

Edit:
Sorry. I misunderstood. You got the input right. But the first input doesn't have anything to do with those two transactions you posted so it's not needed and it won't get dropped by the network just yet (it'll probably confirm before that).
