Hey guys, I've been looking into getting an iPhone. I have gotten into making iPhone apps, and basically I need an ios device. I have an unlocked Tmobile plan, and I really want to stay on that plan. So I need an unlocked device. Anyway, eBay (daily deals) is selling a used unlocked iPhone 5 on ebay for $230, and I really want to spend less that $330. So, given my budget, should I try to find an iPhone 5s, or just pick up a 5? I will probably need one by the end of the month, so maybe there would be an unlocked 5s in the holiday sales? Anyway, is the iPhone 5 a capable device in 2014, and will be continue being capable for at least another two years? (getting software updates and such) I'd like to hear your guys' advice. Thanks.
