Life / Purchasing Fireworks in Poland [6]

I am going to be traveling to Poland next month and I am curious about acquiring fire works in Poland. Are their any retail stores that sell them and is it easy to acquire?

Travel / Wireless Internet connection in Poland [18]

I will be going to Poland with a laptop for 3 weeks. Now I am wondering if there are either a lot of places in the cities where I can pick up a wireless connection or any type of wireless service I can order for only a month.

Also since its gonna be a 9 1/2 hour flight I was wondering what about Internet on airplane?

The main reason is to keep in contact with good friends, post some pictures, and email family.

Thanks.
