hey, welcome to the country! if you have an unlocked iPhone 4, then thats great, at&t uses GSM networks, and verizon uses CDMA, the original iPhone 4 that is not sold by verizon does not come with a GSM antenna, I believe that the iPhone 4s carries both antennas. Im sorry, but the only options for you right now are either AT&T or T-Mobile, if I were you, i'd go with AT&T, they have more coverage than T-Mobile, and offers faster 3G speeds, to be honest, I dont know about the pricing for either networks. Good luck with your iPhone and if you need more help, let me know, ill be happy to assist!
Congrats on getting an unlocked iPhone! There are many benefits of having an unlocked device, of which I'm sure that you are aware of. As victorbraga98 stated, the Verizon iPhone 4 does not use a sim card. If you would like to have Verizon Wireless service then we have an alternative option for you!
