Sorry I can not use Korean letter on this computer .

1)
I pod touch is cheaper than Korea.

It costs about 8900 baht and you can also get refund tax (about 500 Baht)

2)
If you have telsra(Australia mobile), you can use it without changing sim card.

I don't really know how it is happened but it was just working.

So someone who are on the way to go to Korea from Australia and have Telstra mobile, he/she doesn't need to buy mobile nor sim neither.
