Yes. jailbreak with www.jailbreakme.com (straight from safari on the iPhone) then unlock with ultrasn0w. The iPhone first needs to be activated by an official sim before your jailbreak.

Your baseband must be 1.59.00 to unlock.

but all contents of my iphone has been erased should i install firmware first and how
 
What do you mean it's been erased? What's on your screen right now? Connect to itunes? If you can get to the main screen, go to Settings, General, About and tell us your Version and Modem Firmware.

btw apology for taking so long to reply i lost my connection
 
After using the "Erase...," you will have to do a restore. And, since Apple only allows you to restore to latest firmware (4.2.1), do you have old SHSH file saved which then allows you to trick Itunes into allowing you to restore with an older firmware?

If NO, you only option is to restore 4.2.1 which also updates your baseband to 3.10. 4.2.1 JB will be tethered and 3.10 baseband can't be unlock.

If YES, what SHSH firmware file(s) do you have saved?

Right now, even if Tinyumbrella recognizes your phone, you can only save what Apple is signing / sending out which is only 4.2.1. That's why you had to save them already previously. Now, it's too late. Your only option is to restore to 4.2.1 with 3.10 baseband.
