Guys, I am very sorry for posting this so late!!!
The stuff is available already for a while, but I just searched a way get them because it was not working for me!
1. Go to http://daveproxy.co.uk/ or http://goproxing.com
2. Type in http://stardoll.com/en/campaigns/pspuk
3. You have to CLICK on the thing you want. This time it's the guitar, but you are still able to get the other presents (t-shirt and bag) by just clicking on them, too!
Please don't be angry with me, I'm so sorry!!
