My First Purchase on iPhone Failed

During the day, it seemed that there were some problems on the iTMS
server. Neither on iPhone nor Mac, I couldn't only purchase any item
but also even access to the iTunes Store. After several hours, it
looks like the problems were resolved but still cannot purchase on
iPhone. Deal was made on iPhone: I could download songs on Mac by
using "Check for Purchases..." in Store menu.

There must be rushing iPhone users into iTMS during this weekend to try buying songs on iPhone including those of the iPhone Users in Korea, http://iph0ne.blogspot.com :-)
