After updating to IOS 6.1, I'm unable to connect to 3G. The connection will drop to EDGE. I have "Reset the network settings", "Reset all Settings" and even factory restore the iPhone. Nothing works....I am using Maxis. Previously it was working fine...in 6.0.2. Any Maxis user experiencing this?

Yup, stuck at Edge tried everything, nothing works. Even restored back to factory default. Set carrier to manual is only temp, after a while drops back to EDGE. Maxis user.

Selecting Manual Connection is only a Temp solution to connect to 3G connection. Where there is no 3G it drops back to EDGE and does not connect to 3G automatically. Enable/Disable 3G does not help. This is very frustrating since I did not face this is 6.0.2. So its either the software or Maxis. DiGi, Celcom users are you facing this issue after the update to 6.1?

The 3G toggle doesn't work. It works on 6.0.2 but not on 6.1 Seems to be affecting mostly Maxis users? If DiGi, Celcom and Umobile has no issues then it is the carrier issue.

I believe that the 3G issue is Maxis related. My phone is able to switch from 3G/Edge automatically now. Network is set to automatic.
On the first day my iPhone refused to switched to 3G after the OTA upgrade. As of now, 3G toggle doesn't really work(could be iOS issue).
