cocos2d v0.99.4-rc2 is available for 
download:
Highlights (from v0.99.4-rc1):
- An important bug regarding JPG + iOS4 + 3rd & 4th generation devices was worked around
- Templates: Updated to be used with Xcode 3.2.3 + SDK4.0
IMPORTANT:
If your game is using cocos2d v0.99.x and if it contains JPG images, you should update to v0.99.4-rc2 ASAP. Otherwise, 3rd and 4th generation devices with iOS4 won’t render the JPG images correctly.

Thanks for the update Riq, going to convert my previously iPad only project to 4.0 hi-res, will let you know if there are any problems. =)
FYI the proper phase would be ‘worked around’
Thanks, fixed.
