The coming launch of the iPhone in Australia is getting nasty, with carriers spamming other carriers as the battle for iPhone access rages.

According to a well connected source, Virgin Mobile Australia is attempting to spam 3’s iPhone customer registration entry here. 3 doesn’t currently have rights to the iPhone, but states it is negotiating with Apple to obtain rights.

Virgin Mobile is a fully owned subsidiary of Optus, which itself is fully owned by the Singapore Government owned SingTel. With none of the major carriers having yet released iPhone pricing plans yet, Virgin would appear to be well positioned given their current offer of 1GB for $15/ month with existing 3G mobile phones.
