Earlier today, a Twitter user asked @chpwn if they had made any progress on getting Cydia 4.2 ready. Apparently Cydia is already compatible with 4.2 and ready for release following the public release of 4.2 which is supposedly coming out tomorrow. This DOES NOT mean go out and update to 4.2 right now. Please remember that even though Cydia will be compatible with 4.2 shortly after it's release, doesn't mean that all of the Cydia apps will be compatible. After any major firmware upgrade it usually takes a week or two for the application developers to make each individual app compatible with the new firmware. Please hold off on upgrading to 4.2 until we tell you that it's safe. Thanks!
