I hate my phone so much...

Tweet

So I've had my phone (Samsung Gravity T) for a little under 3 years now. At first I really loved this phone; its what T-Mobile refers to as a "phone first" phone, at least that is how it was explained to me. It is technically a smartphone but since it doesn't have wifi capabilities or the ability to download other apps aside from the TMobile store it can't be listed as a smartphone. I noticed about a month ago that my phone has started to get a little slow and sluggish. I turn it off for a few minutes and turn it back on; it speeds up for a little while and then slows back down again, its really annoying. My phone also has the full qwerty keyboard so I can type text messages really fast, but when I am sending the text the send button is unresponsive so I can do 1 of 2 things at that point. Slide in the keyboard and then hit the send button or hit the "OK" key on the keyboard; that also gets annoying when I am trying to watch something and send a text message at the same time; it takes a little more time for me to send it and go back to what I was watching. I know what phone I want next, but I know it is going to be extremely high. I was looking at unlocked phones the other day and this one site that I had been on before has some really good prices. Does anyone know about those China phones? I hear that they can blow up in your pocket though which has me kind of weary of getting one. I could really use a vacation from TMobile as well; I have been with them for 5 years and they are absolutely horrid (although I do like that they don't have roaming charges). I checked their prices for if I was to get another phone with them and they are seriously too high and since we are on a family plan, if the other party on the plan doesn't get a smart phone, I can't either. So many desicions to make. Who else is shopping for a new phone? What are your experiences?
