I've been having this problem for a while. Different roms and stock doesn't matter.
Basically I stop receiving any and all notifications on my gn2 when I'm connected to 4g then when I either torn on wifi or hit a 3g area my phone goes absolutely crazy and I get however many were missing all at once.
It's very frustrating because I rarely use wifi at home being that I'm still unlimited and all.
My network connection works, I still get calls and text messages, just no notifications from apps
A Google search turned up very little help.
