Default SGS2 ATT usuable in Germany with o2?

Hey Guys,

I am situated in Germany and in my opinion, the ATT Versions of the S2 is the most beautiful one. My carrier ist o2.

Is it possible to buy a S2 ATT via the US Ebay and use the phone without any restrictions in Germany?

I guess I need to root it first, then unlock it and then I am good to go? Are these thins easily and safely to achieve? Is it that simple? What about the network, is the american version compatible with the german network? Can I use hsdpa?

Any other restrictions?

Thank you in advance.

the usual problems with US phones in europe... no 3g, but if your only there short term, it may be worth picking up, otherwise just get the euro version with the correct bands.
also i havent checked but there may be a quad band umts unlocked

AT&T version only has tri-band (850/1900/2100) HSPA+ radio. So if your carrier O2 uses 900 band for 3G service, your phone will only work in 2G mode.

International version of GS2 has quad-band HSPA+ and it works everywhere.
