Do you realise the trade-in value for the Nokia 521 is only $5 which is sadly pathetic when knowing that my older Samsung phone is actually worth more than that for a trade-in?
Also, I have over the year sadly discovered that most major companies like airlines, banks, etc, don't even have an App for it as yet nor do they think in creating one which is why I am switching to either an Android or iPhone because I am truly fed up with the sheer lack of App support from major industries that don't think possibly its worth their time & effort to create one for it?
