I've decided that I want to sell my iPhone. I can do without until the 3G is released (making the resale value of my current one plummet). My question is, what rules or regulations (if any) prohibit me from selling my iPhone internationally (specifically Australia) on eBay? I asked for only domestic bidders but someone for Australia bit on my 'buy it now' offer. I want to make sure I do the right thing and protect myself. If anyone is knowledgeable about a similar situation, please let me know. Thank you.
