Ok fixed and push working fine on jailbroken 3g running 3.0..
activated not hacktivated
uncheck icam in applications and uninstall [sync]
SSH to /var/root/Library/Lockdown/activation_records and delete wildcard_record.plist [make a copy to your desktop first]
Reboot phone
When you reboot your phone, it will ask for activation again, allowing you to easily put in your official sim card and activate with iTunes
check icam in itunes applications and install.. when you first run icam it will ask if you want to allow alerts click on allow..
hopefully it will work for you also.. I now have icam sending push allerts..
