Hi, i own an N70 on the 3 network 2 months old and the tom tom 5 wont work on it. The tom tom works fine on my old phone (6600), but on the N70 it crashes could last 2 mins could last 10 but always does the same problem (screen freezes on map) then the phone needs to be switched off to get the phone working again. Any ideas aas im sick of carryine 2 phones.
