5.0.1 (9A405)
sir eto yung version niya.

nyaks! IOS 5 na pala yan

You have to jailbreak your iphone and upgrade the baseband to 6.15 para ma-unlock or openline yung 3gs mo. Unfortunately, you have to wait for the untethered jailbreak. Why? Although, meron ng jailbreak for iOS 5, tethered at semi-tethered jailbreak lang ang pwede. Tethered jailbreak means, you have to use a computer to boot your phone kapag naubos yung battery nya or kapag nag-restart or respring yung iphone in an event of an application crash. Hindi siya advisable for travelling or mobile use. Semi-tethered naman will let you boot your phone ang gain some basic functions like, calling and texting, however 99% ng jailbreak ay hindi gagana, and that goes with the unlock, hindi din siya gagana, kaya useless din yung iphone mo dahil naka-rely siya sa unlock to make your sim work. Besides, semi-tethered has a lot of bugs, especially ultrasn0w, baka mag loop lang yung iphone mo. And sad to say, there is no way for you to downgrade to 4.3.3, dahil I'm pretty sure na wala kang shsh blobs na backup for that firmware.
What do I Suggest?
1st, If di mo naman kailangan pang gamitin yung iphone at may spare phone ka pa, keep it or use it like an iTouch, pwede ka pa naman makinig ng music, watch ng video, download ng apps and play with it and even surf the net using wifi, kaya lang para lang talaga siyang iTouch dahil di mo siya magagamit sa pantawag or text. Kapag lumabas na yung untethered jailbreak, meaning mag-boot na yung iphone anytime na mag-restart or mawalan ng battery, you can jailbreak it and unlock, and use your iphone again, just like before.
2nd, If tethered jailbreak is not a problem with you and you always have a computer to use in case na mag-boot tethered ka, then go with it. Pero again, kapag tethered jailbreak, useless ang phone mo kung bigla na lang mag crash at mag respring or reboot, dahil stuck ka talaga sa apple logo, until ma boot momsiya using a computer, but then again, it's up to you.

I won't encourage you with semi-tethered, baka lalong di mo magamit iphone mo kapag tinamaan ka ng bugs.

I hope that helps, just give me a feedback kung ano decision mo
