hii all
i update my iphone and now i canot call from it .. what to do ?!!
my iphone is 3gs

You didn't provide anywhere near enough information for anyone here to help you. Please let us know the following:

1) What version of iOS you updated to (I'm assuming 4.1 based on the timeframe, but assumptions could lead to incorrect answers.)
2) Do you rely on an unlock for cellular service? (Are you using the phone on the carrier it was purchased from?)
3) Do you know what an SHSH is? If so, do you have an SHSH on file for a previous version of iOS?

If you let me know that as a baseline, I should have enough to get started. Bad news is that if you upgraded to 4.1 and you do NOT have an SHSH on file, you are stuck -- there is no way to downgrade or unlock/jailbreak.

Let me know and we'll go from there.

ooops sorry bro but i do not know alot about iphone
1)i enter to settings->general-->about and look thier the version is 4.0.2(8a400) i hope that what u asked for

No this is fake.. if it is not mentioned on Chronic Dev Blog or Dev-Team Blog then it's a fake and possibly malware/virus.

1. Use The Firmware Umbrella to find out what version of iOS your phone is currently running and what baseband it has
2. Pastebin your last iPhone restore log, so we can see if there was any errors or failures in the restore. http://www.hackint0sh.org/f137/130802.htm
