Life / Unlock iPhone 4/4s in Poland (Lodz) [7]

Jailbreaking an iPhone is not to hard, if your uncomfortable with the process, then a search of the internet will give plenty of tutorials , pro and cons etc. I wouldn't pay for software to do it, all of this stuff is free and well explained.

In Poland there are many small telephone shops and kiosk's in shopping centers as already mentioned, that would be my first port of call.
