Hello. I upgraded my BB 7.0 to 7.1 and I found this problem. I tried inserting my friend's battery on my BB9360 once because my batt is empty. After chargin it, I used my own BB batt and it says "Insert Sim Card -- SOS". I borrowed my friend's batt once again and it detects my network. I replaced the batt with my own later and it worked well. after few weeks, I changed my sim card and the problem occured nce again. I returned my original sim card and nothing happens. My friend is not on my place anymore. what should i do? Thanks! :(
