Need to get a smart phone. What's good?

I thought I'd add my 2 cents. I work for AT&T, the galaxy S III is a great phone, both of my devices are android. I'm not too much of an iphone person although iphone is definitely user friendly. Many people upgrading from a basic phone have no problems adjusting to the iphone. With pretty much any phone you buy you're going to have some issues. The galaxy has some over heating issues, but most of that has been resolved by now. The iphone is having some software issues with ios 6 too. When considering a phone, think about what your network availability is. Where I live both AT&T and Verizon are 4G LTE so the internet speeds are going to be about 10x faster than on the 3G network. Also all iphones before the iphone 5 are not LTE devices, so if you're needing to use the internet, you're speeds aren't going to be as fast. With AT&T we claim the the 4S is 4G but it isn't capable of full LTE speeds.

square is a great application, I believe it only charges you 2.5% of your transaction, many businesses just build that into the price for the convenience of being able to use their debit/credit card. Also check into transferring your consumer account over to a business account. Many phone providers offer discounts and waive upgrade/renewal fees. When having a business account there are also many other benefits and applications that are available to you, so you may want to ask to speak with a small business consultant in order to make sure you're getting the best bang for your buck.

In my opinion the way to look at it is, you need to get a phone that you can grow in to. When you upgrade to a new phone you're signing a contract stating that you'll carry that device for the next 2 years (unless you buy a new one at full retail price, for example iphone 5 is $649.99) many phones that they are offering you at greatly discounted prices, (iphone 4 $.99) are end of life phones, and they're not going to be able to support software updates in the future which means you might not be able to use your phone to its full potential, especially if you're going to start using yours for business purposes.

Good luck, any questions let me know!!
