Well...not sure if it's a good decision but I traded my unlocked iOS4 16gb 3GS for a Nexus One today. I still got mine and my gf's i4 waiting for the unlock. Figured I would try Froyo until the unlock comes out. Was this a good trade?

you do know when the I4 jailbreak comes out that it will work on the 3gs as well..
Iphones always keep better resale then the competition. Any way enjoy the new toy!
Darn I really wish this were true. Can't seem to find an At&t nexus one for under $475 here in Denver. Craigslist has 3gs's galore going for much less...
HAHA I almost traded my 3GS for a nexus one that had a scuff on the corner and was rooted. Only reason I didn't do it (besides the scuff since my iphone is basically new) was because it was rooted. I heard if you root the nexus that voids the warranty. Judging from the bugs that the Nexus one has/have......i held off. While I love the iPhone 3gs......I rather much have 3G speeds as oppose to edge speeds. I even almost traded for a 9700! Decisions...........
