Hello all,
I was handed a mint iPhone 3GS from my sister and she said I could have it. I'd like to unlock it and use it with my current service (T-Mobile). I currently have an original unlocked iPhone (2G?) that I'm using on T-Mobile service as well - love it!
I've tried for hours and hours this weekend to jail break it, unlock it, downgrade it, etc, with no luck. My research online pointed me to a few iPhone forums, but the acronyms and technical jargon completely beyond me. :redface:
SPECS:
iPhone 3GS
4.1
5.14.02
Whatever those mean…as I understand it, 4.1 is slower, so many are down grading back to 3.1.2….and if my phone was still on 3.1.2, I would be able to go to www.jailbreakme.com via the phone and have it unlocked. When trying to downgrade, I read something about SHSH files?? If I don’t have them, I can’t downgrade? Lost here…
My sister is with AT&T, so can I place her SIM card back into the 3GS and then downgrade it?
Lastly, I’ve run across a few online ads that say they will/can unlock any iPhone for $20-$30 bucks. I don’t mind paying, but again, via the iPhone forums, people are stating these sites are scams. :frown:
Sincerely,
- Zishan
