So you want to compare the technical specifications? I suggest going to a site like PhoneArena.com and entering your model number, and then compare that with any other Galaxy S2 that they have on file. I should correct my previous statement--you're right, there can be some minor hardware differences. Samsung also tends to add on other names to their models, like the Galaxy S2 Skyrocket, or the Galaxy S2 Plus, which makes things very confusing.
