OK just been to maplins to buy one for my 3G Ipod.
Now, the instructions that come with this thing are fairly cack so i found the following link on the web.
http://eshop.macsales.com/shop/ipod/bat ... vice/#1424There are various vids for each generation showing you how to fit it. Dont worry about the differing product names as they seem to be the same as the maplins ones.
One more thing to note is that the plastic tools they give you are rubbish. They are just too soft and thick to "break" into the ipod. Use (VERY CAREFULLY!!) a nice thin kitchen knife and insert it about 60mm from the top of the ipod. Once in slide the knife towards the metal part of the ipod so it slides under the metal part. Now lever up the metal part so you can get the plastic tool in. Then follow the video its very well explained!
Of course each to there own but i used the knife cos my Ipod seemed to be welded shut!
Overall getting in is the hardest part, once thats done its a piece of cake. Good luck to those that try it. [y]
