I purchased a brand new iPhone 5 in November. I returned it after 2 weeks because the device was simply not apple quality.
Yes it was very think and very fast and the screen was wider, however it had way too many flaws.
Namely it's navigation was poor and the screen was dark with poor color... oh and the price was outrageous!
I bought a htc phone with google android and it has the best google powered navigation system I have ever seen. I bought a used one on ebay for about 100 bucks and it works fine. The screen is about the same size as the iphone 5, the speed is ok, it has tons of features compared to the iphone 5.
android os has the best navigation I have ever seen.
