The previous argument about Apple not selling unlocked iPhones in the US was due to AT&T exclusivity. Well, that exclusivity is over, yet I don't see any changes. The thing is, the alternate carrier is not another GSM carrier, but Verizon where the iPhone will also be provider locked. Even worse, Apple seems to tighten down their supply to countries where they are selling them unlocked like Singapore, HK, etc, where iPhone 4s that are supposed to be available online are not anymore, and supplies in retail seems to be drying out. Only the 3GS is widely available. The alternatives are even worse (Android, WP7). The OEMs that make Android and WP7 phones are only making handsets with dual-band 3G for the unlocked markets (eg. Singapore) without US 3G support. This really limits one's option in buying these phones for use in the US. Apple and Nokia are the only companies that have quad-band (penta-band in case of Nokia) 3G support. Frustrating.
