Mr. Dulaney adds some other juicy tidbits to the pot. He suggests that Apple has sped up plans to introduce the 3G iPhone. This is due to its lack of becoming a major hit in the European market, where its EDGE data radio simply doesn't compare with phones fitted with HSDPA radios. In fact, many European markets skipped EDGE technology altogether and went straight from the even-slower GPRS systems directly to HSDPA. This means the iPhone has to fall back on the pokey GPRS networks. Trust me when I say that using the iPhone via GPRS packet connections is absolutely miserable.
Lastly, Dulaney says that the 3G version of the iPhone also will switch the display to Organic Light Emitting Diode (OLED) technology. This could help the device balance out power consumption, because OLED displays draw less power than standard LCDs, while the 3G radio will draw more. It also could allow Apple to make the iPhone even thinner, though I dare suggest it doesn't really need to lose any weight.
Despite the rumors, we're still months away from the Apple WWDC, which is the most likely platform Jobs will use to announce a new version of the iPhone.
