I have had the Bold since launch and started having data issues like crazy around january. I waited for an at&t update patiently and I can say after using this new os for a week that it is the real deal. No more bis network drops on 3G and it holds 3G voice for dear life now. I am on a fringe area for 3G but get full signal edge all the time. Around the first of the year they upgraded the tower near my house to 3G but in the Atlanta area it is 1900 band so in house coverage was brutal. My Bold would switch from 3G with bis to edge to EDGE to 3G with no bis. I would go hours with no email unless I used data and it would instantly drop the bis logo again with no email. With the new os all of these problems are gone. It's my understanding that the platform is the radio portion of the Bold and that is what was updated. Also there was some talk a while back that at&t were going to give iphone and bold users preferential treatment on the 3G data network because of all the issues we were having. I'm here to let all know that this update works!
