Jailbroken iPhone 4 with Push Problem

Just bought BeejiveIM with Push. It worked like charm today. All messages got pushed instantly.

However, a few hours later, the push won’t work. No message being pushed at all. I have to manually open the app to see those messages.

Googled the problem and found that the push problem will occur if you use jailbroken iphone.

Hmm, I don’t play games or do anything fancy. The iphone is mainly used for work (email and chat).

Maybe it is time to restore the iphone and use it as is.
