Hi, I dont have the official SIM and my phone is locked to ATT. I need to unlock. So I preserved my BB and updated from 4.1 to 4.2.1. Jailbreak with GP and activated with Redsn0w First of all, its totally worth till now, battery life has doubled, far better performance, better proximity sensor behaviour,everythings fine except that PUSH notification are not working for me. PUSH for exchange server mail is working though. youtube is working. GPSis working. Only apps doesnt show any PUSH notification. I have tested it on a messenger service app (meebo) I know about PUSH Doctor and PUSHfix. While is not easily doable, other charges 6$ I want to know if anyone has faced this and has found a wprkaround. Please discuss.
