The Dell Venue Pro, the first Windows Phone 7 handset to rock a QWERTY portrait slider, has been shoved back into 2011. It had been slated for a Stateside launch yesterday.

Reports have claimed that the delay is down to problems with AMOLED screen supplies. However, Wi-Fi niggles and problems with SIMs were also reported when pre-production models were shown off in stores across the pond.

However you cut it, this is a huge blow to Dell. The tech giant would obviously have liked to get its WP7 cell out and in the wild ahead of Christmas. Now it won’t be available until 5 January, hardly a winning time to start flogging a premium handset.
