I heard i can downgrade bootloader if i had 5.8 so i just had to find out which my bootloader was. Turns out in 6.02! The newest one. Well i folowed this site: How to check iPhone Bootloader version | iPhone | iPhone Heat and now my phone says no sim. Im on tmobile with 2.2.1 fw on 2.30.03 baseband. Using something LIKE turbosim but not exactly that. so i have No SIM and id like for it to say TMOBILE? and actually work again...

Thanks
