Really? He's lucky. I paid for mine when I bought my 3GS with the expectation that the software would be updated - don't think it's too much to ask that they do update it considering it's so that they can continue to compete in the market that makes them money, AND that when they do update it that it works.
Although it would be silly to tell people not to update because there might be some people having some issues I would like to point out that I am having plenty of stability issues after updating my 3GS. So far I have had Safari refuse to run, I have reset settings with no change, my phone no longer connects to my car stereo and when I disconnect it Music, Podcasts, etc, will not play, among quite a bit of buggy stuff happening while actually updating it - this was a far from perfect and dreamy update. I'll try another restore when I get home, however perhaps a lot of people saying how perfect their update is will find plenty of bugs over the coming weeks, or simply don't use much more than Messages, Phone, and Facebook..
An obviously if you pay for something with iTunes, you can re-download the app at no charge - obviously the author of this thread just doesnt realise this..
sorry your having problems, but the majority of us are having no issues
