Around the world with an unlocked iPhone

I’ve been traveling this year with an unlocked iPhone 4S, buying local SIM cards as I go. For the most part, it’s been great — it has made overseas business travel, in particular, much more efficient.

Later this summer, I’ll be starting a guide for those who want to buy local, prepaid SIM cards overseas. In the meantime, I’ve written this article for ReadWriteWeb, looking at the state of iPhone international data roaming, including new, cheaper rates from Verizon Wireless, and the costs and benefits of buying and using an unlocked iPhone.

(This week in Korea, btw, I’ve hit a bit of a roadblock — they won’t let you buy a SIM card until you’ve been in the country for 3 days. By that time, I’ll be almost ready to leave. So I’ve been wi-fi hopping, mostly.)
