Finland was included in the second round of iPhone 4 releases on the 30th of July but there where only 55 phones available in all of Helsinki on launch day. Sonera - the iPhone operator in Finland - published a press release the day before the launch with information about where phones would be available at 7 in the morning the following day. There where 25 phones available at Sonera's own store and 10 each at three different Mac stores.
I decided to try my luck and show up outside the Sonera store at 5 in the morning as I thought standing in line for two hours was acceptable. Experience has shown that if you don't get a phone from the first batch, you may have to wait 2-4 months to get your phone. When I arrived just before 5 I was the 22nd person in the queue and the remaining three spots filled up within minutes. The person at the front of the line had waited outside the store since 6 in the evening the previous day. The two hours went by quickly and it turned out to be quite a nice social experience with some nice and friendly iPhone enthusiasts.
I have not had much time to try out the phone yet, but at least the screen, speed and camera are big improvements over my two year old iPhone 3G.
