Tutorial :
1. Download HotSpot Shield.
2. Just Run it, and click on menu US IP (u will have ip from USA, they got best s.u.r.v.e.y.s).
3. Open Mozilla, Opera, IE, whateva...and go to tools -> settings - > advanced -> web -> then put to automatic proxy search -> OK. Don't close ur web browser. Now put the shield on, wait till it runs on new bookmark (it will look for ip, when its done (green shield on tray), close this bookmark).
4. Go to z8 or playspan and use any s.u.r.v.e.y.s u want.
Thanks.
Also later i will look for hosted better program than HS Shield, cuz it anyway sucks, we got better ip changers.
