Guys, im not sure if this is the right place to post..

But i've jailbreaked and unlocked iPhone 3g to 3.0 using redsn0w and unlocked using ultrasn0w.

Used to be firmware 2.1 and was using turbosim.

Now not using turbosim anymore. direct sim.

But , whenver i insert the simcard, it seems that the phone is very very laggy.. whatever applications i run will lag .. But when i remove the sim , it's smooth as ever.

Is this a bug or is it my firmware which is installed wrongly or corrupted?

Ok, i fixed the lag problem . Solution was just restore to OS 3.0 again and re-unlock it..

Now its as smooth as ever.
