^Were that the case, I'd surely take back that wish. xD!
Granted, but just because you aren't stuck in that form doesn't mean you aren't stuck in a huge tin box near the center of the Earth (it's heatproof. :D) in the 1800's, where a cell phone won't work. Plus, there's no food in there, and there's twelve hungry bears in the box. And one of them has rabies. The bears are all on fire, too, and there's gasoline all over the floor of the box. BUT! The box makes you immortal, so you aren't in mortal danger. You're just in immortal danger. And the bears are immortal, too. :D
...Basically, you're immortal and stuck in a box for eternity. But you can still shapeshift! :D
I wish I wasn't too lazy to get the remote.
