Considering a purchase.
If you've upgraded from the iPod touch 4 to iPod touch 5 have you noticed a increase in wifi speed or reception?
Didn't have an iPod touch 4 - but do have an iPad 2 and my new iPod touch 5.
My touch 5 has much better reception and range than my iPad. An example: I have a 52-step staircase leading down a bluff on my property. Can't even see my house from the bottom of the staircase. My iPad's never picked up the signal that far from my house. My iPod shows three bars.
Am very pleased with it.
As the owner of 4th and 5th generation iPod touches, I've noticed that the 5th generation has far better reception (and therefore speed in some cases). The 4th gen used to lose connection a few hundred meters away from a building with a router, but its sucessor has full bars in the same places.
I've also noticed Bluetooth never skips while the device is in my pocket or behind something, which beats the 4th gen.
