doesn't the irex has a capability to hop onto the 3g network in the USA? can't you just modify the settings and hop onto another 3g network? i'vegot a contract for my cell phone with swisscom. i therefore are able to use the 3g network. it seems me that my dr800sg should be capable to use the same network, even without putting in a simcard. i probably make mistake or miss something. could someone explain this to me?
