This is a most excellent place for technology news and articles.
Although I am not experienced with iPhone prices, shouldn't a non-official replacement cost somewhere between $30 and $50? I tend to repair my Android phone batteries every 2-3 years at home, and alongside light software mods they become impressively more usable in the long run.
