2) Still in Seoul now. My Samsung Galaxy Tab and HTC HD2 can roam automatically with my postpaid Celcom sim cards.
Sadly, both my Wife's and my iPhone 4 with Celcom sim cards can't detect the network... A bit bodoh I might say...

So, only using our iPhones' to surf using free Wifi network at the hotel and some cafes or malls...

3) Any universal adapter would do. No converter needed...

Hello, I hope you guys can help me out with these:
1) have anyone stay in Pencil Guesthouse and Seoul Backpackers? I'm deciding between these two, so would like to hear your opinions.
2) Can iPhone 3GS, HTC Diamond 2 and Samsung Galaxy tab roam in Korea? I understand that as long as has 3G, then we can roam there?
3) How is the power plug in Korea? Is it use universal power adapter would do? Or need any converter?
I understand that these information should have been mentioned before in this thread, but there's a lot of pages, and I apologize for not having enough time to read. I'm traveling there on next Thursday and would need urgent information. This thread is very useful and helpful in guiding me to have arough idea of where to go, what to do, what to eat and etc. I will definitely visit this thread still when I'm in Korea and keep you guys posted :-)
