Hey guys I got my friend who owns a X6-00 . His recent problem baffled me and I got no explanation to it . The gag goes like this , he has RIM SIM with 2G Net pack on it .And while using it, the EDGE suddenly goes on hold [the E icon with the cross which happens during a phone call] even when there is no phone call and it refuses to revert back . He is unable to connect to the net using the access point for at least 5mins . Then after several reboots it connects for 5-10secs and then again the problem arises . But when he inserts AIRCEL SIM and works on that , the net on 2G works flawlessly . And another problem he faced was that while he was using a 500mb limited pack on RIM SIM ,he was getting 400kBps on UMTS mode but when he recharged it again the speed on UMTS mode is capped at 9-10kBps while on 2G he is getting 32-40kBps .
