Summary: Nice, convenient Android phone, even though designed more than 3 years ago. QWERTY keypad helps you to type really fast and much faster than on any screen keyboards of iPhone, tablets and so on. Officially upgradable to Android 4.0.4 ICS, has fast Snapdragon CPU 1 GHz, lots of RAM for a phone (512 Mb), SD slot, HSDPA, etc. It is also compact. Disadvantages: fast battery discharge (only 1500 Mah), too little internl memory - 400 Gb.
Summary: I bought this phone to use abroad. I had it for less than two years. The wireless connection was always slow. I updated the software, and the phone wouldn't restart. Looking at the support forums, this seems to be a problem that is not unusual. When I called Sony for support in the country where I am living, they said that they would not fix the phone, even if I paid, because I didn't buy the phone here, even though it is a model sold here.
Summary: The Xperia Mini Pro SK17i I bought through Amazon.com was defective so I returned it and bought the SK17a here in Tokyo from Amazon.co.jp. SK17a is my first Smartphone and Android so I'm only now enjoying the benefits of smart devices and now understanding the reason why they are called "Smart", and I am giddy. But I won't go into comparing it to my previous cell phone and why I hate it so much because it's too much to list.
Summary: By now the machine it's out-of-date but despite the plastic finish this cellphone is a beauty. I got it dropped on a bucket of water by accident and after some research and cleaning (whole dissaembling), it keeps WORKING! I still use it because there is nothing like it with a real keyboard out there.
Summary: I bought this phone as I wanted an android but I prefer QWERTY keyboard to touch-screens, and this is perfect. The camera is great quality with lots of features like panorama and you can also edit videos/pictures. Apps run well, overall the phone is great. Only cons are: The memory isn't huge so I strongly recommend an SD card. The battery life isn't great (although that's probably because I've been using it a lot since I got it!) and the loud-speaker quality is poor.
Summary: This is a pretty good phone except for the dysfunctional alarm feature. If you touch the phone wrong while your alarm is going off it will clear the alarm display (snooze or dismiss) from the screen. The phone does not allow you to turn the alarm off from the alarm settings, the only way you can turn off the alarm is to pull the battery. CRAZY............I use my alarm everyday.....so this is a big annoyance for me.
Summary: It works well, and the Internet browsing is very fast. I am really enjoying the touchscreen and the keyboard functions. Availability of wifi is very convenient as well. If you talk a lot and use wi-fi a lot, the battery will last for almost two days. I use this phone in the US with T-Mobile, and I have never had any problems. Based on my research, it can work with any provider that uses SIM cards, so it should work with AT&T too.
