Tips and between: SmartPhones

First of all, you choose a smart phone, do not take because of the design, ask what's on the 


phone, what features, what quality of camera, what operating system (that did not wish to go a few times and replace or buy and then not allowed to change) 

First:
You buy the machine check if he has a manufacturer's warranty or insurance, if the manufacturer's warranty (eg iPhone) if you are not American then there's warranty would have to buy a new appliance or pay for repair a lot of money)
First of all, remember there are devices you downloaded take place from the field applications of the device and memory of the phone (eg Sony Ericsson Xperia x10a very new model 2011),
Turn off the WIFI when you do not use) because it will finish you the battery)

Some facts from devices with operating systems:

iOs
1 - devices are locked, not can I use them almost nothing. 2 - Most users of the product or other Americans who simply hacked it in Cydia 3 - Let's get to know the facts if you're not an American iPhone after one year manufacturer's warranty dies then lost a lot of money, because Apple considers them to another client like oxygen. That's why there is no warranty. And not iPhone 4G a day. I tried to open a user name did not give me free after not even send me a password for approval, a bulky phone, and I had a problem in iTunes called Apple's representative in my country and got treated like dirt, "Call to the United States" (remind you not all rich)
In one word IPhone waste of money that each year they'll feel a new model out and maybe buy another one. One word is not good. 

Android
1 - Open phone without any locks 2 - do not use the Android operating system did not love her. Who. Who just do not understand it at all just a dream to hold. 3 - the internet is faster 4 - faster device + view as the Rotel and jumps as in disgustingly iPhone
