According to a report in Fortune, AT&T is delaying the launch of its first 3G BlackBerry handset until August following concerns stemming from a technical glitch that affected the handset's call quality. The BlackBerry [1] 8900 was originally scheduled to launch in June, according to the report, which speculated that the delay could also have been affected by the much anticipated launch of a 3G iPhone in June. Research In Motion already has a 3G BlackBerry Global Edition running on Verizon Wireless' network.
