Time to upgrade. Apple overlord Steve Jobs just introduced the all-new iPhone 3G ($199-$299). Besides the faster 3G wireless connection speeds and all of the previous revolutionary iPhone features, the new model also gets built-in GPS, better battery life (10 hours of talk time on 2G networks and 5 hours using 3G), a flush headphone jack, and iPhone 2.0 software with support for Microsoft Exchange ActiveSync, the new MobileMe web suite, and a bunch of new downloadable applications from the iTunes App Store. The iPhone 3G also sports a new (and slightly thinner) glossy case in standard Apple black or white. Both 8GB (black) and 16GB (black or white) capacities remain. The iPhone 3G will go on sale July 11th in over 20 countries.
