Hello everyone. I recently unlocked my iPhone using redsn0w, on the firmeware 5.0.1 and Baseband 05.16.05. After Jailbreaking I could rarely get service, and decided to restore my iphone, so I did so using iTunes restore option. I am still not able to get a signal for more than a few minutes at a time. I have read some forum posts, and watched some videos, and have seen that you can fix it by updating your baseband to 6.15.00, however, I also hear that that greatly limits your ability to restore or update the iphone in the future. I have also already tried a network reset, and various sim card tricks. Does anyone know how to fix this searching/no signal issue? I am no longer concerned with jail breaking my phone, I just want to have my phone back. Thank you!
