When it comes to subsidy rumors for Apple's 3G iPhone, some are more believable than others. In this case, we'll leave the likelihood judgments up to you. Readers of French tech site PCInpact say that they are getting calls from Orange with offers of an upgrade to the upcoming Apple wonderphone. For only 50€, readers say they have been told they can swap out their current-gen iPhone for the new one. Or, say the French, the upgrade will be offered at a "generous" discount. With Orange's recent 3G iPhone distro deal in the books, we had to give this rumor some airtime. Either way, this could mean everything -- or absolutely nothing -- for those of you residing stateside and looking to bump your iPhone this summer.
