Remember the Samsung Omnia Pro B7610? Think Samsung Omnia II with a slide out keyboard. It was due to pack an AMOLED display, a rocket fast 800MHz CPU, and a capacious slide-out keyboard. It could have been a big competitor to the now ubiquitous Touch Pro2. In addition, the B7610 had the 1900UMTS band (like the Omnia II), meaning that for many in the US, 3G on AT&T would be possible. It was also supposed to see a release in September, then October, and now it may be released this month. We’ve talked to two mobile phone retailers and both have no explanation for the delays, except that the Samsung keeps pushing back the release date without reason. We’ll keep an eye on the situation, and we hope that Samsung gets the device out before the HD2 Pro is released (or whatever keyboard-packing device is derived from the HD2).
