    No luck. I taped it pretty good and was still able to kill my signal by holding it the way I normally hold a cell phone.

    You know, he might have something here. I used an eligible upgrade for one of my other lines to upgrade the phone on my personal line. I had to cut my old regular SIM so it would fit the MicroSim tray. Once I put the home rigged MicroSim into the phone I noticed the reception problem. I went to AT&T a couple days later and got a real micro-sim and once they installed it, the reception problem was gone.

    I just got a case -like any sane person should for their pretty pretty iPhone 4- and I haven't had issues since.

    So, no issues AND my phone is protected.

    +1 for index.

    So.... just have a plastic sim tray right?

    I bet you you it's AT&T cards that are causing the problem.

    We would know if it's AT&T sim if we had an unlock for tmobile and then we can test that!

    I think it's the software my 3GS with 4.0 does the same thing

    I am on t-mobile in the UK and have no signal issues at all.

    UPDATE: I actually can only get my signal to drop if i have wifi switched on .. Anyone else getting this issue?

    Just tried this and used electrical tape. It seems that I get more bars now when it's sitting on my desk without me touching it, or it's just a sweet spot I found.

    But one finger on the seam and down the bars fall.

    If you look at the tray where the sim card sits it is painted so it won't short out. I tried to some tape there just to try it out and I still get the same signal drop. Seems
    Like if it did short out the phone would not work at all.

    ATT will be handing out free sim trays soon

    Thank you for the tip.
    Its obvious that it will not fix reception issues , this fix will not boost reception should any one think it would. However it does help to provide better reception when holding the phone and helps with the issue of dropped calls on the iPhone4 where the 3GS would not drop calls.
    Based on my testing this easy fix does help, so thank you again.

    Mine is off centered as well. I placed a piece of tape where the gold contacts of the sim touches the tray. Signal still drops, although not as much. I'm also having slow wifi and 3g speeds as well.
