From this blog I read:
http://www.iphonedownloadblog.com/2010/11/27/optimize-app-icons-retina-display/
Basically batch converts and makes retinas or something
You download mobile terminal(make sure its for iOS4!) and iretiner from cydia
Then u just open mobile terminal with your defaults:
sn:su
pw:alpine/custom
type in:
iretiner
1
y
y(to respring), n(to not respring)
All non retina icons will now be retina.
Worked for like 20 of miens and did a freaking great job.
