So, I'm running a fully jailbroken and unlocked iPhone 3G on 4.2.1 FW. My T-Mobile SIM Card is running perfectly, until today. Whenever I'm in the subway or in the basement in my school cafeteria, I tend to lose service, which is not unusual. But the weird thing is, when I'm outside of school, I still get no service or reception. The only way for me to get service back is when I press the "Reset Network Settings" button, which can be found under Settings<General<Reset<Reset Network Settings It gets extremely annoying, especially when I have to reset the network settings EVERY DAY. Does anyone have a solution for this? THANKS!
