I've recently updated my iPhone to 4.2.1 and was trying to get Springjumps to work on my phone. I was able to get my custom springjump icons to load onto the phone, however, the icons got smaller. I used the same icons that I used when I was on 3.1.3, I didn't change anything, I just copy and pasted it. The dimensions of the icons are at 150x150 and 80x50, it appeared fine on 3.1.3 but now it's become to small to see.

Is there a reason as to why the icons got smaller or would I need to remake them?
