Thanks,I appreciate your input.
No, not WIFI. I don't really know that I trust the speedtest because even after acceptable numbers, (according to AT&T Tech. Support), my browser was still super slow.
I downloaded System Status:
Disk Used 9.2 GB
Free 4.3 GB
CPU Usage fluctuates very quickly between 3.0 to 14.8
Idle fluctuates between 35% and 95.0%
Avg Load fluctuates 0.9, 0.85, 0.89
WIFI Info
Network Connected - Yes
Network MAC, IPSubnet Mask, SSID, BSSID all look ok ...(?)
Cell Info
All looks ok
I spoke with AT&T Tech Support and he said that for the last 11 months, my iPhone 4S was still in their system as an iPhone 3S and that this would have caused problems, he fixed his side; I restarted and also re-set network connections, ran speed test which was within AT&T's normal range, except the upload speed was slow.
AT&T also informed me that one nearby tower was not functioning properly.
The tech. rep. and I concluded that the best thing to do would be to wait a couple of days to give repair crews time to repair the tower, then, if the speed doesn't improve, call them back.
Thanks again for responding, I was ready to throw the darn thing out the window!
