I've heard mixed results regarding forcing the iPhone to 3G operation only (so that it doesn't switch between 3G and Edge).. this is supposed to improve call consistency (read: fewer dropped calls - which i seem to have a lot of problems with).

  1. does anyone know how to do this without jailbreaking?
  2. otherwise, any tips on getting better reception/reducing dropped calls?

I'm no expert, but it seems to me that if the phone is switching to Edge it may be because the 3G signal is poor, which seems like you would experience even more dropped calls since you stop it switching to edge. –  Matt Jul 24 '09 at 16:21
good point, Matt. Perhaps i should disable 3G alltogether and see how that works out. –  NoCarrier Jul 24 '09 at 16:25

If your phone is constantly switching between 3G and EDGE, it is likely that you are in a really spotty 3G area. You would actually be better served attempting to force EDGE instead of forcing 3G, because if you are forcing 3G, you are potentially forcing it to lock onto the network with the worst coverage/reliability for your particular use.

You can also try this, electronicholas.com/2010/08/force-iphone-4-to-always-use-3g but by first backing up your device, then changing the file in the backup, and finally restoring the backup. It should work but i havn't tested it. Will try today though. –  Maciej Swic Jan 12 '12 at 7:40
