Hello everyone ...

Ok so i got this iphone 3G on os4 that i jailbroke and unlocked with ultrashow... its now on the bell network

Problem is i have like 3 bars reception at best and whenever i turn off cellular data and 3g the phone loose reception and tells me no service available ...

I did reset all settings but it didn't help the problem... just reboots the phone and then i get my 3g back on with the phone reception... but as soon as i turn off the 3g , same problem again no service available

anyone had this problem or know a solution ??

Thanks in advance
