iPhone 4 speaker not working after greenpois0n jailbreak

[meatmeltmebro]

My roommate and I both have iPhone 4's running 4.1.2. About a week ago, I jailbroke mine using greenpois0n and haven't had any issues. Today, I jailbroke my roommates using the same exact method I used. Everything seemed fine at first, but then he discovered that when he makes calls the ear speaker doesn't work. The speakerphone part works fine, but for some reason it doesn't work when he holds it up to his ear.

We've tried restoring to backup and restoring to default multiple times and it became un-jailbroken (Cydia disappeared) I've had an iphone for over 3 years now and I've messed up jailbreaks before and it all fixed itself easily when I restored.

Any ideas as to why restoring the phone isn't working? Any help at all would be greatly appreciated. Thanks

Sounds like a physical problem with the phone, probably just coincidence it happened after jailbreak. Restore to stock firmware an take a trip to apple store.

Yup, sounds like a hardware issue.
