A unique conversation came up the other night between myself and a friend, Exactly how many different variants are there of the Nexus S and why? So after a little research, here's what I came up with:
1) Model: GT-I9020T
Carrier/s: T-Mobile USA, Wind, Mobility
Bandwidth: 900/1700/2100
Screen: Super AMOLED
2) Model: GT-I9020A, GT-I9020F
Carrier/s: AT&T, Rogers, Fido, Telus, Bell
Bandwidth: 850/1900/2100
Screen: Super AMOLED
Note: Rooting differs from I9020T
3) Model: GT-I9023
Carrier/s: Most countries outside of north america
Screen: Super Clear LCD
Note: Rooting also differs from I9020T
4) Model: SPH-D720 (Nexus S 4g)
Carrier: Sprint
Screen: Super AMOLED
Bandwidth: 800MHZ/1900MHZ/2.5GHZ
5) Model: SHW-M200K, SHW-M200S (Korean Variants)
Carrier/s: KT, SKT
Screen: Super AMOLED
I guess we can now see that although the Nexus S is technically a GSM or CDMA unlocked device, one device will not work across all bands. This question came up because both my friend and I are T-Mobile customers, and have model I9020T. We have a mutual friend who is also a T-Mobile customer, but bought the I9020A. He was able to connect to T-Mobile's network, but could not connect to their 3g bands (only EDGE).
The reason behind posting this was to inform people, that if they were looking to purchase a Nexus S, this could save them a large headache. This allows you to be sure you purchase the correct model number for your respective carrier.
Hope you find this post usefull,
As always, rock on...thanks for reading

the epic brought over to tmo worked on 3g, I'd look how they done it there might be hope for your friend
Tried it, not compatible with the Nexus for some reason. Samsung does something that the other manufacturers don't do, and the typical IRL hacks don't work :( Thanks for the heads up though :)
