I bought this phone back in March or April, right when Straight Talk was first coming out. I was looking for a replacement to my Verizon prepaid because it was getting very expensive. I then stumbled upon this, and after doing some research, I found out it works on the SAME network! I chose this phone because I liked the QWERTY style keyboard. Yes, they keys are a bit small, it just takes some getting used to. I like the big screen as well. You just have to keep in mind that this is NOT a blackberry. You CANNOT do the same things on this phone that you can a blackberry. I call this the "poor man's blackberry" because its so much cheaper to run, and not with all the bells and whistles.
With the internet... yes, it is slow. No, it is not anything like any other smart phone. It even states in the TOS that it is the most basic internet available. You cannot stream video on this phone, load a full page of facebook, ect. Even checking e-mail can be taxing at times. But, for the money, and what I pay per month to use it, its worth it to me.
The phone operation itself can be a pain at times. When you go into your pictures, it takes a while for the screen to change to start loading pictures. At times, if you try to push buttons too fast to go through the menu, it will freeze up, and you have to pop out the battery to restart it. Pocket dialing is HUGE with this phone. The keyboard lock will quickly become your friend... trust me.
One thing I do like about this is I can make my own ringtones. I have bluetooth on my computer, and I have it synched up with my phone. I can send music to my phone, since it can act as a very "i really really need music right now" mp3 player. I usually send very short mp3 clips to my phone and use them as ringtones.
The camera is pretty basic. Its 1.3 megapixels, and if you have it for the highest quality, the zoom feature is non-existent. If you set it to a smaller reso, then the zoom can be used... but even then its not the greatest.
The calls with this phone are VERY CLEAR!! I had a samsung phone in the past with Verizon, and it was a more expensive phone that was very hard to hear me on. I also live in an area with little-no coverage, and I get at least 3 bars sitting in my house. I can even make a call from my basement, where most other phones and plans, I had to find a good spot outside... living in minnesota, this was NOT fun most of the year.
Even with some of the issues the phone has, its still very worth it. Even after losing it in a snow bank recently, it still works perfectly. The battery life is fading fast, but in the beginning i only had to charge it every other day, with heavy use of texting and calling. I use the internet sparingly, but like I said before, its very limited as is.
One thing I do recommend for this phone is investing in some sort of case (silicon/gel/or otherwise) and a screen protector, because of the size of the screen its more prone to scratches. Its a great little investment, and with some searching on ebay you can get them VERY cheap.
