Nope, What you buy is what you get.
The ipod does not have a memory card slot, so no memory card will work with it.
No.
no sir
no
The Ipod touch does not have an memory card slot for an SD card or any type of memory card.
ipod dock
It depends, if you have an ipod shuffle it is either a 2 gb or 4 gb while the sansa clip+ starts off at 4 gb with a user choice to add a memory card but the ipod classic has 160 gb but it is bulkier so it just depends on what size you want or if you just care about memory
no you can not but they are certain apps you can get to have extra space on youre ipod\iphone like dropbox
No. The iPhone uses its internal memory. And a SIM card.
I think it all depends on the model of your iPod. But I can give you a website, you can have a look and find out whether there is a SD card suitable for your iPod. http://www.dinodirect.com/iPod-Accessories/
The iPods use a few different ways to store their data. Here is the list... 1). The iPod Classic Hard Drive 2). The iPod Nano Flash Based Memory 3). The first iPod Hard Drive 4). The iPod Shuffle (1-3 G) Flash Based Memory 5). The iPod Touch Flash Based Memory 6). The iPhone Flash Based Memory
I am assuming you are referring to the apple itouch. No, you can't change a memory card on a itouch. If it is full I would suggest rotating your music/videos in and out or buying an ipod classic
