[sony_psp] Please Help!

Ok, just bought the psp slim, star wars, medal of honor heroes, and 
medal gear solid, and can't get online with any of them! I am going to 
starbucks and using the free t mobile hotspot and have 100% signal.  I 
can get on the internet fine.  The star wars wont let me register or 
use the existing gamespy id I made up.  Medal of honor(the old one) 
says that ea servers are not availible.  Someone help before I give up 
on online with this thing or buy a router for the house and waste more 
money!
