I don't want to unlock it, I want to jailbreak it. Two different things. I want to be able to connect a bluetooth keyboard to my phone amongs other things.  And I want multitasking, and I want some other free cydia apps. (Among other things i want the home screen to look like the one in a htc device, you know so it will be more functional and there's tons of stuff that a jailbroken iphone can do that a normal can't)

True the massive number of apps came latter, but it came for a reason. I heard it's fairly easy (I might be wrong) to write an iphone app. Most apps are based on html javascript and css, and now all windows phone 7 apps will have to be based on .net and silverlight, which are harder to do for a total novice.

Hmmm I see, so then the iphone would be paradoxically the most 'open" system because of the most developed jailbreaking community, and it's more popular = more crackers and hackers are  will try to hack and crack it.

Ah I see in the us, wikipedia doesn't say anything about poland, but since it's such a common practice on  the polish ebay and other such sites to advertise modding of consoles and jailbreaking of iphones, I guess it's legal here.
