I had the same problem all day edge not EDGE and as a result, no pushed
email, internet or mms. I thought it was a BIS outage, but after a call to ATT
when I realized it was too long for a BIS outage, I found out my BB data plan
had been taken off my account. Why? I have no idea, it just was. They apologized
and added it right back on while I was on the phone.
I was not very happy about this at all...
When you get edge this is what it means:
EDGE and GPRS = data service
edge and gprs = no data service
