You do not need to wait. Those firmware updates (like Nokia's Lumia Cyan update) and carrier updates are separate from the Windows Phone 8.1 Update 1 RTM update that is now available.
A Puppy's Life to Dog-dom. Weeks 1 and 2. These weeks are very quiet in that the puppies can not see or hear for the first 10 to 15 days, they can not regulate their own body temperature - they are totally dependent on their dam and their environment for warmth, nutrition and stimulation.
A good guide is that dogs can control their bladders for the number of hours corresponding to their age in months up to about nine months to a year. (Remember, though, that 10 to 12 hours is a long time for anyone to hold it!) A 6-month-old pup can reasonably be expected to hold it for about 6 hours. Never forget that all puppies are individuals and the timing will differ for each. Monitor daily events and your puppy's individual habits when setting up a schedule.
