In nokia N70, you can switch between GSM Mode or Dual Mode (GSM or 3G Mode). And in order to use 3G from N70 cellphone, you must set your mode to "Dual Mode", but if we move to some weak 3G spot area, this phone automatically switching back to GSM Mode.
I was wondering, is there any way to "lock" nokia N70 channel to 3G (UMTS) channel ? So I can still connected to 3G (UMTS) network if I still in 3G coverage and the 3G signal is weak.
Thanks for your comment,
