iphone 3gs wont activate not reading sim

[PoSsUm]

I gave this phone to my daughter bought it jailbroke and unlocked.I have no clue what version it was on.Anyways she did some restore not knowing,and now the phone goes to the language screen then next tries to activate but cant.Tried different sims and no go.Please how can I get this fixed and help would be great. Ithink Iseen 6.15 something I havent had the phone long in my hands to remember.

I try using redsnow it goes through the ramdisk starts loading stuff then it keeps saying please wait mounting roofs as read only error the no successful firmware do wnload after 60000 ms!! Giving up

I have tried redsnow with firmwares and custom firmwares after that with itunes and still nothing my fix is going to be a sledge hammer.I hate iphones.
