Is there any down sides of bying unlocked iphone for T mobile?

I'm tired of android battery life, so I though about buying a new iPhone 4s from eBay and using it for t Mobile, is there any down sides of doing so?

No but T-Mobile doesn't have the service but they are ok

I purchased a factory unlocked iPhone from Apple and I use it on T-Mobile without any problems.

Tomorrow (March 26), T-Mobile will make an announcement that is presumed to include information about the iPhone for T-Mobile.

I would also suggest you not purchase an iPhone from eBay. Too many people who did have received fakes or phones that can't be used because they have been reported lost/stolen, etc.

  • Why is my iPhone 5 screen not changing sides when I turn my phone sideways? My iPhone 5 screen got wet today because it was raining outside. You know how it changes sides when you watch a netflix movie. Since I came home the screen doesn't change sides. What to do?
  • What are the down sides to jailbreaking your IPhone? I want to jailbreak my IPhone 4S. I want to know if there are any down sides to jailbreaking it? Some people told me that if I jail break it then my warranty on it is gone. I know the good things about doing it but what are the downsides?
  • My iPhone 4S won't turn anything to the sides? Won't turn videos nor my keyboard. It's been like this so ce the IOS 7 update. Apple had to long of a wait I was waiting 30 minutes and I just hung up. Can somebody help me? @debbie I don't even know where the auto rotation is at all I use it for is calling, tecting, and my email.
  • Is there any free software that can flip my iPhone screen upside-down? The bottom 3mm of my iPhone's screen is unresponsive and it's actually a very vital part of functionality. I know that it'd be best to repair the phone, but in the mean time, is there any software or tweaks I could download/use to make the screen flip upside-down when i turn the phone that way?
