Need help regarding Unlocking Iphone 3gs ios 4.1(bb 05.14.02)
Hi I am a new member here, I just got an iphone 3gs, new bootrom, firmwire 4.1, baseband version 05.14.02, my pc is using windows 7 (32bit). I need to unlock the phone to use it as there are no official local careers here (Bangladesh).
I have seen several threads/guides/videos to jailbreak using redsnow 0.9.6b5 and unlock with ultrasnow and most of them has stated to upgrade to ios 4.2.1, but as it will be tethered and involves complicated restoring process with custom firmwire, I want to stay unlocked at 4.1 os. is it possible? or upgrading to 4.2.1 is a must for jailbreaking/unlocking with redsnow/ultrasnow (macs are also rare here so using pwnage tool will be difficult)
If i do try to jailbreak/unlock it now with redsnow/ultrasnow (remaining in ios 4.1) and something goes wrong will it be damaged permanently or i can restore it to stock ios 4.1 and try the process again? (i have read the thread regarding restoring and seen that firmwire 4.2.1 and onward wil be unable to restore to original stock firmwire, but as i will be using ios 4.1 it is possible to restore to stock 4.1 firmwire even with baseband upgrade to 06.15.00, just need to be sure ). i have got shsh of only 4.2.1 saved and tinyumbrela says others are not available as it is too late so downgrading from 4.2.1 will not be an option either.
sorry for bugging so much with all the questions, the thing is as iphones are rare here i had to pay almost 650$ to get just a 3gs (i know it was stupid on my part as i could have gotten an iphone 4 for that price if i had bought it from the US) and I want to be sure. without jailbreak and unlock its just an extremely expensive ipod for me...any help will be apriciated, thx...
