I keep hearing rumors about a AT&T 3G compatible Venue Pro coming out soon. After I recently discovered you could delve deeper into the Venue Pro’s Diagnostic Menu, I learned of a hidden feature to fix radio bands. Dell allows you to choose from 4 GSM bands(850, 900, 1800, and 190) and 5 WCDMA bands(850, 900, 1700, 1900, and 2000). For those of you don’t know what these numbers mean, AT&T’s 3G network runs on 850mhz and 1900mhz. Since we see options to fix these bands, it could mean that the radio supports it. It could be the case that Dell simply added compatibility with AT&T’s network should they decide to sell such phones in the future but not give these Venue Pros the necessary hardware to utilize these settings. For now, I cannot test if the 850mhz WCDMA band works because T-Mobile does not support it and the Venue Pro is SIM locked to T-Mobile. But if the Venue Pro does support the 850 band, Dell should start selling it unlocked and market it as a pentaband phone.
[Update:] Thanks to Benjamin Ries’ comment we have discovered and verified that the Venue Pro does not have pentaband support. The option exists in the Engineering Menu, but the hardware is not there to support it. Changing the settings allows you to disable select bands but if you allow for a band that is not supported by the hardware, nothing changes. With
