I am new to the iPad but have been with iTunes for a number of years. I am a Canadian who now lives in the USA for six months of the year. On my past visit to the states, I acquired an iPad for X-Mas so in order to use it, I had to register with iTunes under our US address. I used a different e-mail address to register at that time retaining my Canadian address for use in Canada. Now I am wondering if it's OK to use both accounts on my iPad. Are there any restrictions I should know about and will I have any problems using both the Canadian and US accounts simultaneously? Any advice would be much appreciated, keeping in mind I am a novice in computer and iPad land. Thanx
