iPhone: 3GS
Itunes version: 9.2
Issue: Issues after upgrading to iOS4, cannot browse 3G or Edge.
None of the following steps resolved the issue.
Solution: Full restore via iTunes 9.2, a reset using the different reset options in the settings menu will not work. Some have also reported that toggling airplane mode ON and OFF worked for them.
