The things it would need for me to think about buying are:
antenna issue sorted
50% better battery life
64 - 128GB
A5 processor
8MP - 12mp camera
Same size screen
Design more like the 3G curved back
50+fps HD video
Faster graphics
Better speakers
30% lighter
White colour
4G
Lower Price
The battery life is very important as the iPhones battery life is rubbish.
