Froyo not out for the Galaxy S? You got to be kidding. I brought in my Galaxy S to a Samsung service center and it came out with Froyo. Some of the Galaxy S they got in display also got Froyo. Mine got the official ROM ware build JPA. It should be noted some ROM builds require to be brought in the service center, while others can be done through Samsung Kies. I don't really know why but mine fell to the first group.
The Froyo updates are spreading fast among phones first among Europe and Asia, including India, Philippines, Malaysia, Indonesia, S. Korea, Singapore, Hong Kong, Thailand, the UK, France, Germany, Netherlands, Nordic countries and so on. Various carriers now have updates in effect, including Vodafone, and new ones are being announced, including Bell Canada, 3 UK and T-Mobile UK among the latest. Australia appears might be soon, on Telstra. The slowest it seems were for the Americas, especially the US, since it appears the updates are going to be hitting Latin America soon.
