I want to buy a (T-Mobile Nokia 1661) unlock it and run it in boost mobile network. i bought a boostmobile gsm sim card on ebay but im a little confused. Boost mobile offers 2 networks, IDEN and cdma according to their coverage map http://www.boostmobile.com/coverage/ I am in the u.s., i called the customer representative at 1888boost4u but it sounded like he didnt know anything about it, i was told "if it says boost mobile its u.s." So can you tell me if it works. Also i just want boost mobile for their internet service @ $0.35/day please tell me if your or were or know about their internet service tell me how it is @ a scale of 1 through 10 1 lowest 10 highest. My main question is can i use the boostmobile sim card on any gsm unlocked phone? or it wont work because its on a different network? thank you.
