    Have you tried a restore to custom fw already after this has happened? If so it might just be a flaw with that baseband.

    Do you have 3g enabled? Under settings? I had the same problem but someone told me to turn off the 3G as the iphone does not recognize tmobiles 3g service. It works off wifi and edge. Its a drawback but still worth it in my book.

    If you have SHSH blobs saved, you can restore. No problems.

    Did you reset network settings?

    You can restore fine to a lower fw with the iPad baseband so long that SHSHs are available. The baseband itself cannot be downgraded.

    I have a 3GS at home with the exact same problem. It constantly loses signal and can't get more than 1 bar or so. I only have t-mobile sim cards at home so I can't confirm weather it is a hardware or software fault. It also occasionally after being left off for a long time resorts to the connect to itunes screen whereas itunes will direct me to restore the iphone.

    I have SHSH blobs for 4.2.1 and 4.3.3 and it is on the ipad baseband.

    I have pretty much just written off this phone has I don't know what the issue is.

    In my area T-Mo is a bit weak. On the 3GS, 2-3 bars are normal, but an old Samsung cheapie is rock-solid.

    Has your phone ever been repaired? During my last repair a side-bar grounding pin was forgotten and the single dropped to 0-1 bar.

    Yeah I believe mine has been repaired, given to me by a friend who worked at a cell phone repair store, he no longer is there now though. Is it possible my 3GS has the same or similar issue?

    Also my iphone 4 (T-Mobile) next to it gets a solid 5 bars when the 3GS struggles to hold 1.

    That little-bitty gold-colored ground pin made a significant difference in my reception

    A nice shinny gold pin should be on the bottom side, attached to the dock connector and touching the outside silver rim.

    I'd love to know more about this itty-bitty gold pin! What is it called, where do you get it, how much does it cost, etc.
