Cydia Sam tweak

[john lee2]

Try using cydia Sam tweak to unlock my 3GS. I was using my active AT&T sim card. Now sim is not recognized on my iPhone 4's. Can anyone help? I need my phone!!! Thank you in advance

To my knowledge the SAM unlock bug has been long fixed. As to why your iPhone 4 (or 4S - couldn't tell from your post) isn't recognizing the SIM card - I don't know. What exactly did you do with SAM and did you touch the other iPhone in the mean time?
