Hello, I can't find anything with exactly what I am looking for. I upgraded to the Iphone 4 this past weekend. love it so far, but I want to sell my 3gs. I have already moved it to OS4. I noticed that phones that are unlocked go for more which makes sense, but I'm confused by all the jailbreak/unlock paths. it appears that you if are on 3GS and on iOS4 (and old bootroom) you have to downgrade to 3.1.3 and then upgade to iOS4? so i guess my question is this. I want to sell it unlocked but my 3gs is on iOS4, not jailbroken, has old sim inside. . .what are my options?
