I have an iPod touch 2nd generation. The iPod is 100% perfect physically, it has spent its entire life in an OtterBox Defender. Unfortunately the battery is shot. Which is a strange issue because the iPod is actually "new" old stock because I received it back in February of this year brand new in the box. I opened it myself, broke the seal on the packaging and everything. I received it as a gift, so I have no receipt, so there is not any way to get this problem covered under warranty. Anyway, my question is if I send it in to Apple for their designated price to replace the battery. It says they will send a "replacement iPod". My question is, will the send another 2nd generation iPod, or will it be updated to a newer model? or are there any reputable places that will replace the battery "on the cheap"?
