Hello everybody;

I'm owner of a Nokia 7610, i'm really happy with it. By the way, i'm using it with SFR (a French GSM Network), since the beginning of the last week, my phone started to get lost connection with the network. It started to get disconnected/disattached on gsm network. I'm just restarting, and i just get my network back, but it becomes a little bit annoying.

I have done a full factory reset (by going over Settings menu) and nothing has changed.
My phone version is : V4.0421.4 / 22-05-04 RH 51

Suggestions welcomed.
Thanks in advance.
