A little bit of back story: A couple months ago, when T-mobile started their no contract plans, I called them up and got them to give me the new no contract rates for the remainder of my 2- year contract (pretty nice of them). My monthly bill for four smartphones is now only $100, which can't be beat. Now, however, I've gotten sick of tolerating my old, buggy, and outdated Sidekick 4G. Anyone who knows anything about this phone will tell you how many issues it has had since its release. Well, anyway, since I can't lock in a two-year contract anymore, the next phone I get I will have to pay full price for. I'm not too picky on which phone it is, but I don't want to spend anything more than $400. I've been looking at the Nexus 4 and possibly a used GS3. What do you guys have in mind? I also came across the Galaxy Nexus. I can buy the unlocked GSM version for $230 or so on ebay. From what I can tell, the Galaxy Nexus still seems like a pretty modern phone, but idk. Like I said, almost anything will be an improvement over my phone. I want either the best phone for $400 or the cheapest decent phone for significantly less.
