Need help before doing job
 

Dear supporter i got 3 set of aiphone 3GS with firmware 4.1 and base band 5.15 for jailbreak and unlock . Ok i know it can be done by latest version of redsnow but some of my seniors told me that dont do any JAILBREAK of 3GS bcz after jaibreak if you REPOWER the set will hang on APPLE logo and there is no solution for that.

I just want to ask to the experts of 3GS to kindly guide me IS THIS RIGHT and SHOULD I JAILBREAK THESE SETS or IS THERE ANY SAFE METHOD TO DO ALL THIS PROCESS and after UNLOCK ,set should not go on threaden position ?

Looking forward for experts opinion .:(

there is no problem if ur phones are 4.1 version , just update your baseband to 6.15 with redsnow then unlock it with wifi, teetherd jailbreak is in 3gs 4.21 ver not 4.1 so go for it.

Thanks brother , i am going nto follow your advice and will let you know accordingly. Thanks again.
