T-Zones stopped working

[henrygrins]

I have an iPhone 2G 2.1 software unlocked using custom fw, and I put "epc.tmobile.com" in the APN, and it was working 2 days ago, and now it's not. I keep getting "Could not activate cellular data network". I was using youtube last night on the edge network, and then POOF it stopped working (possibly at midnight on the dot, I can't be sure). I have T-Zones (or "T-Mobile Web") and like I said before, it was working perfectly last night until a certain point, then just switched off. Any ideas?

Thanks in advance!

I should mention I have the edge network logo "E" next to the network, so it seems to see the edge network...

Reboot, do the settings all over again, turn WiFi off and on again.

A simple reboot worked. Thanks!
