Push Notifications not working-iphone 4s, ios 6

Hi, im new here and i hope im not breaking any rules :)

recently i restored and updated my iphone from jailbroken 5.0.1 to the latest ios 6.

i had push problem on ios 5, that didnt work for some reason, only when i enter the app (like whatsapp) it conects for like 2 sec and then i get the msgs. so i thot the update will help cuz maybe the jailbreak was bad or somethin.
i checked all option related to push and everything is checked ON.

i also tried iPusher which tells u if u got puch problems. and its stuck on "please wait" which means somethings wrong (used an online guide).

ive been looking for a solution ALL DAY, but no luck!
maybe its an ios 6 known issue, or physical problem !?

so please help!

10x in advance and have a good day peepz :)
