Samsung E105 Software & Data-cable HELP

Hi, i got this SAMSUNG E105. It comes with pre-installed settings of T-Mobile and T-zone. As i does'nt live in UK nor we got T-mobile here, so is there any way we can reset it for our own MMS/GPRS settings? Or can we re-install its software, OR change its software, with that of E100!??

ONE MORE THING, As i am a new user of Samsung fones, so it true that All samsung fones use same data-cable, Like they use same charger?

Waiting for Answer
