If you signed a 2 year contract you will have to pay for two years, at least that's how it is in holland, would be surprised if they give away xperia's for 200 bucks..cheers
If you do it carefully, and use the Sd card flash (only for the rom, not for the HardSpl i believe), the chances of it are really really small, but i guess there's always a chance..
But trust me, its more than worth it :)
There are really good guides and how-to's on the Rom development page, go read the stickies there. You need to HardSPL first, then flash a rom. But dude i should advice you to read a bit more before just plugin your $500 phone in and start doing things that could damage your phone.
