    This is a problem similar to one I have had before, but I can describe this better. I have an unlocked iPhone running on tmobile and it was working fine for a day, but after I hooked it up to iTunes, it now periodically gives me a "one bar" without a carrier or give me searching... for a long time and then "no service" in a place where I know I have service, whenever I turn it on. when this happens it has no carrier options under settings. This only happens about 1/3 of the time I turn my phone on, so there must be some way to fix it. I'm thinking that there could have been something that itunes did when I synced it, or it just happened. I have tried everything I can think of, and I am desperate, so please help me I want to be able to use my unlocked iPhone!!!

    Have you restored it and tried setting it up as a new phone?

    (obviously you'll need to preserve your baseband...)

    Yes, and it seems that it works fine until I sync it to itunes

    I have the same problem I preserved my baseband when upgrading to 4.1. I then used Ultrasnow for the unlock but now I'm getting the No service ~ 1 bar no t-mobile problem. This only occurred after I powered off the phone.
