I am new to this so excuse any dumb statements. My Treo 680 was working fine with the Vodafone network until a couple of weeks ago. It now appears to make a connection to the network (green arrows appear in the signal bar area) but cannot display webpages on the Blazer application or download email. I used the SIM card with a Mobile Connect card in a laptop, which worked fine. I perfromed a factory reset on the device and even had a second new Treo 680 to test - which has exactly the same problem. Is there anything else that I can do? Has the network changed somehow? Has anybody else in NZ had a similar problem recently with their Treo 680? Thanks.
