Symbian has been dealt setbacks in recent days as both Nokia's N97 and Sony Ericsson's Satio appear to have been pulled due to likely quality concerns. The former isn't available on most carriers and is now no longer selectable through Vodafone UK; while visible online, choosing it redirects shoppers to the N97 mini. No explanation has been given, but it's suspected that the more stable Symbian release on the smaller, newer phone is the cause while the original N97's initial firmware was the cause of numerous complaints.
