If the solutions had nothing to do with an IP address, I believe it would be ok to turn the title itself into representing that it was a twitter related problem.
I am against redrawing the Question itself to suit answers it may receive, that type of thing could lead to more answers that are "stock" answers for specific issues.
If it turns out that Changing the IP was the solution to the whole problem, not just what it says in the title. I would be ok with it becomming the ONE true "change your IP" question.
Titles are not questions, although they should represent the question. The users title could have represented the question better.
