X-box Live on Sprint Wireless?, Somebody help quick please - I'm about to kill my children Options

[DEATH]

My GF got her internet through her cell phone company Sprint - Lord knows why. It costs too much, It requires a huge deposit [at least with her credit] and it can only hook up to one computer at a time. All of this sux but my most immediate problem is I just got my Kids an X-box 360 and they play on-line at their friends house constantly [he has what I would have bought - a regular ethernet cable internet]. But so far I have not been able to figure out how to set this up through either her computer or with the wireless internet device plugged directly into the X-box 360. The kids are "bored" now and anyone of you that has kids knows that can make your house into the 7th level of hell really quick.
Now I know a bunch of you are into X-Box and a bunch of you are into computers so can someone please tell me how to do this so I can get back to work killing the gremlins in my swapped Celica?
Come on - please help a guy out?
