i learned my lesson when my first iphone 1.0 was stolen in the subway, and i didn't realize there was app called an iphone LoJack to track down stolen iphone, so i didn't have that app installed at the time. now, i just bought an iphone 3g today. I don't want to repeat the same mistake again. is there anyway to track down this iphone 3g IN CASE of theft? could i still install that lojack app? is it compatible with 3g version? (but i think i would need to jailbreak the phone, right?). just trying to be cautious this time. all advices are welcome.
