My iPhone 4 has been switching between 3G and O all day. It is now doing it when the phone is just sitting on my desk. I'm not moving and watching the 3G switch to O and back again every once and awhile. I originally noticed it happening every time I tried to download new email or get on Safari, every time I tried to use data.
I just did the *228 thing and no help. Data roaming is turned "on".
My speedtest is showing:
Ping:1256ms
Download: 0.07mbps
Upload: 0.00Mbps
Absolutely horrendous!
Any ideas?
