I dunno how true is this news(most likely it's rubbish)... i had been staying in BKK for 1 year now... but all i can say is there is NO 3G network in Thailand till now. The government still havent officially awarded any 3G licenses to any operators....
eventhough most of the ppl in telco industry are saying should be in 2009(had been saying this since 2 years back that license will be out soon)... but i can see ppl from AIS,Dtac and TRUE are planning aggresively on 3G network deployment since Q2 2008.

if any operator will get 3G iphone, it will certainly be AIS which belongs to Temasek Group.
just look at Globe in Philippines which also has the 3G iphone plan soon... Globe belongs to Singtel....
