iPhone 3G 2.1 says no Sim Card

So, Apple decided all of the subscribers should update SIM Cards?

This is ridiculous!

Specially in Mexico, we have a long weekend for the hollidays, there will be no help for us until wednesday!

Operators like AT&T (in Poland ERA) don't know anything about 2.1 update and new sims, i've received today a new one, and still I'm unable to activate..

Patryk with the new SIM you still receive the no sim error?

Same problem with my non-hacked iPhone. Movistar. Argentina.

Unfortunately YES, a brand new from my operator.. and still no sim error..

same problem here Telcel Mexico, i need buyed a new sim card 10usd :S

I have the same problem in Spain with MOVISTAR.... WHAT IS WRONG ?????? My iPhone is my work tool !!

Problem solved. I inserted another SIM from the same company and the iPhone started to work. Then i reinserted my original SIM and it started to work fine again. Extracting and inserting the same SIM didn´t work for me until i used a different SIM previous to reinsert the original one.

Mismo problema. Tendre mañana que pasar por MOVISTAR a pedir una nueva SIM.

Segundo dia que tengo el IPHONE y...zas. No tiene perdón... 😟

I also happen this problem when upgrade to firmware 2.1
my iPhone 3G from Hong Kong, no sim lock model, the sim still work on another cell phone, no problem.
this is error on the upgrade firmwar2.1
I remeber i open app store, which show not hkapp store, is japan store,when i login my app store account, the iphone will jump up screen to standby, after i tune off iphone and tune on again, it become this problem.
who can solve this problem. thanks.

Apple Inc should be responsility this issue,

I will take this iphone to 3Dealer to checking.

It seems Movistar Colombia, has a hard problem with Iphone 3G, it's the second time i need to go to the store and change my SIM again. But it is true 2.1 Upgrade fries not only olds Sims but new sims too. My new sims has 15 days old.

Additionally i tried to restore it, but i had to put it another sim for success.

Maybe a problem with Simcard lot, i mean manufacturing fault or mistake of compatibility.... Movistar please! think of their clients!!!!

iphone 2nd gen, No Sim error 24 hours after install of 2.1

southern California

Same issue - "No SIM" within 24 hours of 2.1 update. Spoke with AT&T iPhone support. Suggested action - power off, remove SIM, power on, power off, power on, insert SIM. Recovered fine, no repeat issue (yet).

I am also in Mexico. I just purchased an iPhone 3G from Telcel today. I was seeing the network with no problems until I installed the 2.1 patch.
Phone Serial:88835XN8Y7K
SIM CARD:89520 20608 39113 4822F

The SIM also says telcel v3.0

Any help would be greatly appreciated. If you can tell me some of the problems associated with this, I have connections with the team at Telcel and would be able to offer technical support.
Thanks
