How do you get past the Pokemon blocking digglet's cave in Pokemon soulsilver?

Answer 1

you go to the radio tower in kanto and talk to the man in the brown hat, he will then update your radio app on the pokegear. next you go back to the Pokemon blocking diglets cave, go to your pokegear radio app and grag the little dot to the top and move it aroun until it says pokeflue, wait about 5 seconds, exit the pokegear and press A to the Pokemon, you will then battle it, you may chose to catch it, run from it, or knock it out (by the way its a snorlax level fifty).
