For those of you that are using the true unbranded/unlocked Galaxy S from the UK here in the states, here are the MMS/Internet settings. Go to Settings/Wireless and network/Mobile Networks/Access Point Names Hit the menu button, then "new APN". The settings are as follows: Name: AT&T (or whatever name you like) APN: wap.cingular Proxy: leave blank (Will read: <not set>) Port: leave blank (Will read: <not set>) User name: WAP@CINGULARGPRS.COM (Not sure if it's case sensitive, but I left it all capital letters) Password: CINGULAR1 (Not sure if it's case sensitive, but I left it all capital letters) Sever: leave blank (Will read: <not set>) MMSC: http://mmsc.cingular.com MMS proxy: wireless.cingular.com MMS port: 80 MCC: 310 MNC: 410 Authentication type: none APN type: internet+mms I initially started researching this after I wasn't able to send or receive MMS. I could send regular text messages just fine though. I read posts all over the place and none of them were really defnitive in regards to the Galaxy S' settings. I tried some configurations that would allow me to send and receive MMS, but then the Internet wouldn't work. In other cases I would get the Internet but no MMS. So after putting it all together, and trying a bunch of different configurations, the above is what I've confirmed as working. Just wanted to post it up so others don't have to spend the time I did. Hope it helps.
