Saurik is a busy busy bee. He just optimized Cydia for iPhone OS 3.0 and now it’s working on WinterBoard 3.0No news on a repo to update if you are already jailbroken with icy. Currently the only way to get Cydia 3.0 on your 3G iphone is thru an updated QuickPwn for Beta 5.
NOTE: If you upgrade to 3.0, it will change your baseband and yellowsnow unlock will be non-functional. Furthermore, as of now you will not be able to downgrade your baseband unless you are on a 5.08 bootloader and be stuck without a soft unlock.
