Bad Signal after 4.1 update (no it'snt an hardware issue)

Hi,
I upgraded my iPhone 3GS from 4.0 to 4.1 yesterday. After the upgrade the signal is very poor.
Entering in field test i get:
-92 db if the phone is on the table
-110 db if i take it in hand.
Moreover now the phone loss signal in place where before i can make call:
1) With 4.0 i can make call from elevator, now with 4.1 i get: searching, and then no signal.
2) Same thing in the stairs
3) at home where with 4.0 i had full signal now only -89 db.

Don't say is a hardware problem, because the phone was perfect before update to 4.1. There is no problem with tower cell.
The problem is the update to 4.1 and the related update of the baseband.
Please do somenthing and quickly because now in these condition my iPhone 3GS can't be used like phone, but only like mp3 player.
My operator is "Tre Italia"
Thanks

iPhone 3GS, iOS 4

I had the same problem. I was dropping calls where before could have a full conversation. Try resetting your network settings. I still have low signal but am not dropping calls anymore. Go to Settings - General - Reset. Click on reset network settings. Give it about 5-10 mins and you should see an improvement. Also make sure you disable the "processor hog" called spotlight search. Everything you type is compared to the search and slows everything down possibly taking processor from signal. Go to Settings - General - Home Button - Spotlight Search and uncheck all categories. Should speed things up a little.

Well I join you all guyz too... I recently upgrade my phone to 4.1 with new baseband and ufff was a terrible mistake cause now i cant make calls in places I could before, I live in Puerto Rico and here AT&T Rules with signal and 3G internet. Before In every place i got full signal with 3G running fast and now 3 bars poor reception poor internet slow as ****. I need to say apple must focus to fix real problems no give more of them.

I hope this problem can be fixed cause this about new calculation in signal and that with less bar ya get same performance is a lie speed now slow calls drops a lot. True must be tell.

Same here:(
This is just ridiculous:( I upgraded my iPhone 3G and now it cannot be used as a phone anymore, cos the siglan is so poor that i cannot make most calls in locations where i had full signal befor upgrade. Thank u Apple, i am going to buy some "spare" mobile till u fix it, but for the future, pls, test ur SW products better for god sake!!!!

Same problem as everyone else. iPhone 3GS upgraded from 3.x to 4.1. Used to work perfectly everywhere in my apartment. Now it drops the signal whenever I move around and sometimes I even can't get a signal. I never had a problem before using iOS 3 OS's.

In Singapore with Singtel as carrier. I tried turning off 3G, but problem still persists. Come on Apple, throw us a bone.
