How to use my Iphone when I'm in Thailand

I'll be in Thailand for a month and will not have Wi-Fi. There are internet cafes but what use will my iphone be while I'm there?

I went to Thailand once, but that was 13 years ago while I was in the 1st grade. So I'm not sure now.

Two answers. Entertainment & Media.

Unlock your iPhone, get a 3G SIM when in Thailand and use data as per your requirement. Problem solved. You can contact this person (arghyle@rocketmail.com) who can help you with the factory unlock.
