Push Notifications not working on any app (Whatsapp, Beejive, Mail) after update 5.1.1, Help!
I'm gonna try to be clear with my problem. I have a Gmail Account working on Microsoft Exchange, for IM messaging I'm using Beejive IM with Push and I'm also using Whatsapp. Before Updating it to iOS 5.1.1 all Push notifications were working flawless, however, after I upgraded it to 5.1.1, I began having troubles. After 1 minute of having the Iphone locked, I don't get any push notification, nor on the email, nor on the Whatsapp, neither on the Beejive. If I unlock it and I re-open one of them, for ex, I go to check my contact list on Beejive, I get all the mails, and all the instant msgs that people had sent to me after I locked my iPhone; it's like, my iPhone was locked for 30 minutes. In those 30 minutes people sent me 4 msgs on whatsapp, 4 msgs on beejive and 4 mails. Once I unlock my iPhone and I go to one of the 3 apps (mail, whatsapp or beejive), I get the 12 items (4 msg from whatsapp, 4 msgs from beejive and 4 mails) at that exactly time. It's crazy, it's like, with this new update push notifications got disabled for every app or what happened to my iPhone on this upgrade? I really need help. WIthout Push, none of them apps works cool for me. I'm using Iphone 4 on a 3G network.
Ps: I tried restoring it x3, I unistalled the apps, mail, etc and nothing worked.
PS2: If someone is using whatsapp or beejive im with push on the new iOS 5.1.1 and push notifications are working good for them, please let me know it so I will know it's my iPhone hardware problem to bring it to technical service
Thanks in advance
iPhone 4
