I have been noticing my nano's battery getting lower and lower. Now im about below 50% the promised 14 hours, and i realized that entitles me to a battery replacement under the apple care and protection plan. But when i take it in to get repaired will i receive the new edition of the nano in return? And my current ipod is the 4 gig which i bought at $250 so if i do get the new version will i get the 8 gig which now retails at $250. Thanks in advance for clearing up the confusion, because i have conflicting opinions from multiple people at the moment.
