I really regret not getting one of these cases earlier. The colours looked so good that I couldn't just decide on one, I ended up getting two. I cost me $13 for two which is an excellent price when you see the quality of it. The case on it right now is sky blue and I think it is so cute and works well as everything is light blue themed on my phone currently. I also have the white one which looks amazing. I plan on swapping cases every few weeks.
One of the best things is that my boyfriend can use my phone now and won't complain about not being able to find the power/volume buttons as this case has holes for them.
Shipping took two weeks to Australia, for anyone with the i9020 I definitely recommend this case 110%
