damn this is getting old, I really hate this jb thing. that's why i switched to n900 and never look back even 5g come out. And I am glad i did, i did throw my iphone into the swimming pool because it's dead when i plugged it in my car charger. that was unbelievable quality there.

My 3GS works perfectly after blackra1n. New baseband improves my t-mobile signal strenght a bit.

Reset network to fix wifi, use original sim card to avoid youtube not connect, re-install app to fix push notification. Now Perfect!

Delete the app and download it from App Store again see if it will fix it. That's what i did after blackra1n my phone.

That's not entirely correct!
I am on a T-mobile with 3GS in US, Push Notification works just fine for me.

Blackra1n & sn0w issues:

no wifi : resetting network (if you restore the data from backup, wifi may break again)

youtube not connect: use orginal sim that came with iphone or an legit iphone sim when restoring or updating new firmware.

Push notifiction not working : delete the apps and download it again from Apps Store.

Beside those issues above i've seen, Everything else works perfectly so far. Thanks to GeHotz

I just want to share something I learned after jailbreak and unlock with blackra1n & sn0w, Push notification is not working, delete and reinstall the app from App store will fix it. One by one if you have many push notification apps.

If you have the original simcard that came with the iphone, then put it in when doing the restore. I did that and go through the whole unlock process than just put my T-mobile sim in and resync my data. Or you can install the pushfix from this source in cydia. h t t p : / / c y d i a . i p h on e i l . n e t

Don't buy, they are all scam!!!!

Damn, it's just a joke and i got -6pt, people can't tell the difference anymore i guess...

I hope that Dev team will release the updated pwnage tool today, so i can get iphone updated and back to work on Monday. :)
