hello, im just throwing this question in here to see if i get an asnwer before i get on the phone with a couple of companies.

Ok, i have a Razor V3 and a Razor V3a from iWireless and US Cellular respectively, im trying to find out what other companies can i use those phones with as im looking to swtich providers. Now i dont know what type of network does US Cellular and iWireless use, but both phones have SIM cards, i have read a lot of comments talking about type of network having to be the same, but for my 2 cases what actual companies can go to? thx in advance.
