    Don't Use Compressed Air to Clean your iPhone 4

    I got lucky today....I was at my friends machine shop, decided to blast my phone with air to get the dust out of the speaker/mic ports. Bad move, it killed my mic. People could no longer hear me.
    Made an Appt, went to the apple store, got a replacement. Had 4.0.1! Whew! Jailbreak still possible.
    Only bad news, I cannot restore, cause I have no SHSH blobs stored for the new phone. So I better not need to restore until a JB is released for 4.1 (fingers crossed)
    I still consider myself lucky.....

    Yeah, thats a dumb move. I once used compressed air on a digital camera to clean the lens only to push the dust deeper into the device. Last time I ever used compressed air for anything delicate.

    Did you try to use TinyUmbrella to get your 4.0.1 SHSH? I dont know if Apple has stopped signing 4.0.1. As of 2 days ago, they still were. Or now that you are JB'd go to Cydia and click on "Make My Life Easier" and it may still be able to save your 4.0.1 SHSH. Has anyone confirmed that Appls has stopped signing 4.0.1 yet?

    Yes, they are done signing. I downgraded my new phone yesterday at work and hit the Cydia button, but when I tried Umbrella when I got home, they weren't signing any more. I just came in under the wire.

    Just gotta be careful. I have used my garage's compressed air to clean out the dust from the 30-pin port on mine before, never had an issue. But I always keep the pressure regulator turned way low, and my air line also has a dessicant canister and automatic drain valve in the bottom of the tank to prevent any moisture from coming through the air line.

    Yes, Tried TinyUmbrella, no go...I chose the "Make my life easier" option, but I don't think Saurik can sign my phone without using apple's servers.
    I just have to prey that I won't have to restore...

    also compressed air can cause moisture damage if you get that cold shot and it condenses. Just a bad move.

    never use compressed air on ANY electronics, period, unless it is very low pressure.
