I'm also having the same problem where my Edge randomly stops working, even with a full signal. I've found that turning the phone on and off fixes it, but obviously it's annoying. I think mine also started sometime between the 22nd and 25th (don't quite remember) and I've always had push support on as I have an Exchange account synchronized (one of the big pluses of 2.0 for me!). Has anyone tried calling T-Mobile yet? I'm considering calling but am not sure if it's an iPhone or network issue.
