I follow a BB guru with his own website: Salomondrin
I do believe he travels internationally but I recall him indicating he is based out of Mexico. He may be able to provide you with a solution to your issue. He also twitters and the account name is on his website.
He is also good about answering questions on BB messenger, his PIN: 212DC279
I am posting that because he also freely posts it on his website.
Good luck and let us know what your solution is. I travel to Mexico occasionally to visit family and might haul my Storm over next time for the heck of it.
