Hi i have an Iphone 3gs 16gb i recently jailbroke it using redsn0w and it was working fine and everything seemed to be normal, last night i started having reception issues where my phone would say it had no service so i would put it on aeroplane mode and off so it would re search for service and it would come back until this morning i could not get any at all. i restored my iphone through itunes and then i got a message saying insert a valid sim so i jailbroke it again and then now i have no options for push notifications and it doesnt even search for my carrier and have restored it again and no jailbroke it and still its not searching for carrier service and even worse i have nothing coming up on the phone no apps or camera icon, messages, contacts nothing at all the screen is just completely blank what do i do can anything fix this please help!!!!
