Alright, Engadget Mobile readers. Time to put your thinking caps on. BenQ-Siemens appears to be trying to announce their new business-oriented tri-band phone, the A58. They're having some trouble doing that, though. The folks over at Slashphone have pictures of a no-frills candybar, clearly labeled "A58." BenQ-Siemens' site itself also has an A58 which looks nothing like Slashphone's. Could it be that BenQ-Siemens posted the wrong pictures? To us, the official pics look an awful lot like the CL71 we first told you about a few months back. At any rate, their specs appear to jive with one another; expect a basic "voice-oriented" phone with Bluetooth on the 900, 1800, and 1900 bands. Even if we squint, we can't buy that these are the same phone. Are we missing something?
