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Summary: By now the machine it's out-of-date but despite the plastic finish this cellphone is a beauty.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.
