Hello people... Yesterday I unlocked my iphone 3g with ultrasn0w 1.2 on iOS 4.2.1 and it works fine except Push Notifications. I have downloaded Push Doctor a few times but push notifications don't seem to work... Any suggestions???

How did you jailbreak? Did you use limera1n? If not, what program did you use for hacktivation?

I don't think that limera1n can jailbreak/hacktivate 4.2.1, so they must have used redsn0w or pwnagetool.

If the user restored from a previously hacktivated iTunes backup *after* jailbreak/hacktivation this might create this kind of problem.

The most common cause of push certificate problems is NAT/DNS problems. Try setting your DNS on the iPhone to use google's DNS 8.8.8.8 and 8.8.8.4

4.2.x is much more aggressive about checking push certificates than previous versions. See this link for clarification.

I have not yet received a definite confirmation from the primary developer behind push doctor that a installing legit certificate via push doctor will fix this (my understanding is that it should). I can only surmise that the original poster is doing something wrong or the problem is network related.

There should be NO need to request a certificate more than once from push doctor. That just wastes certificates that others can use.

well, I used pwnage tool for iOS 4.1 and BB 6.15.00 and couldn't get push notifications to work at all... I restored yesterday to 4.1 with sn0wbreeze 2.0.2 and with the first try of push doctor it worked fine... but with sn0wbreeze ipsw I get some apps to crash and itunes gives error : could not start a session with the iphone and DOES NOT backup...so I wan't to move again to iOS 4.2.1. But will push then work? I have now kept with ssh my working certs.

BTW: Olethros, did you know that your nickname means "total dissaster" in greek??

Try http://www.iclarified.com/entry/index.php?enid=13089 after jailbreaking with pwnagetool custom IPSW.

Sn0wbreeze doesn't include the correct kernel patches for some apps to work properly. This has been an ongoing problem (which might be resolved in the future).

Of course I know that, it's why I chose it.

Olethros translates roughly in ancient Greek to "destruction", but often with a positive connotation, as in the destruction required for and preceding renewal.
