Alright.

So, I've been baby sitting for my sister as of late at her new house, her boy friend has a 32 inch Widescreen flatpanel HDTV, xbox 360, etc. He lets me use it, I'm really digging Saint's row and GRAW2.

I plan on buying a xbox 360 in a month or so when I got the money, I wont have a HDTV or anything like that for along while, but my thread is not about HDTVs.

I'm curious as to how I can get my profile, my achievements, and all of that from his xbox 360 to mine (When I do get one :D.)? Can I buy a memory unit and transfer it(one that plugs in the front) with that? And how would that work uploading it via xbox live?  And would I be able to take my achievements and profile from xbox to xbox with it as well?
